The Stonebook Mini occupies a niche where there does not seem to be any competition:Despite a number of niggles mentioned below, it is well worth considering. While choosing I could not find a comparable or better performing machine of similar weight and size that did not cost over twice as much as this.11.6", 1.2Kg, 4 core Celeron N3160, 8GB Ram, 500GB drive, 1366 x 768 matte screen, VGA, hdmi, 1 USB 3, 2 USB 2, ethernet, SD card reader, wifi, ethernet, replaceable battery.

-- STONEBOOK MINI PURCHASED APRIL 2017 This document is available in two formats http://www.cs.bham.ac.uk/~axs/laptop/stone-mini.html http://www.cs.bham.ac.uk/~axs/laptop/stone-mini.pdf This machine was supplied by Stone Computers Ltd, the main computer supplier for my university. https://www.stonegroup.co.uk/ Online specification: https://www.stonegroup.co.uk/hardware/notebooks/stonebook-mini/ Small print on the back of the machine indicates that it was made for Stone by Clevo Co, in Taiwan. Overall I am very pleased with it, despite several niggles mentioned below. I spent a considerable amount of time looking at alternatives and could not find anything that matched the key features of this specification (including the 5 year on-site warranty), and did not cost over twice as much, e.g. the outstanding Dell XPS13 (width 13.3 inch, with higher resolution screen, and more powerful CPU), but smaller storage. -- SPECIFICATIONS Specifications of the Stonebook Mini, based mainly on: https://www.stonegroup.co.uk/app/uploads/2016/02/Stonebook-Mini-Datasheet.pdf (The datasheet, but not the web page, erroneously states that there are two USB 3 ports instead of only one. The pictures make the actual configuration clear.) Operating System Supplied Up to Windows. 10 Pro (Although I use linux almost all of the time, I ordered Home Windows-10 in a 100GB partition --probably over generous-- for occasional use, and for diagnosis in case of a warranty claim for a hardware fault.)

So these figures (April 2017) should be regarded as approximate guides: Stonebook Mini without operating system: GBP 315 + VAT (including 5 year on site warranty) My options: Microsoft windows 10 home edition GBP 68 + VAT (Pre-installed in 100GB partition) Spare battery: GBP 40 + VAT Spare charger: GBP 30 + VAT TOTAL GBP 453 + 20% VAT No competitors? While trying to decide what to buy I looked at lightweight offerings from all the main suppliers, e.g. Acer, Asus, Dell, HP, Lenovo and some others and found no real competitor that could meet my requirements. Nothing else came with a five year on site warranty, for example. ===============================================================================
-- OPERATING SYSTEM As I am a minimal Windows user, I asked for the Home Windows 10, in a 100GB partition, leaving the rest free. I suspect 100GB was too generous. But the machine boots off a usb stick with Gparted "live" so I can shrink the windows space later if required. I prepared a Live XFCE Fedora 25 memory stick and booted from that to run Gparted to set up boot and swap partitions a root partition, a spare root partition for future upgrade, a small partition for encrypted stuff and a large partition for /home, with /usr/local mounted on that partition. After preparing the required partitions it installed Fedora 25, though as usual it was a minimal system and I had to use the standard facilities for updating the operating system and downloading many packages that I use regularly. Fedora 25 was installed in a 14GB root partition (which is larger than necessary, but allows a lot of temporary stuff to be saved in /var/tmp). Fedora 25 plus the CTWM window manager, works very well on this machine, though I had to do some experiments to find ideal settings (e.g. font sizes and default xterm window sizes for a smaller screen than I am used to). For a while I had an obscure text 'smearing' problem in xterm windows and some other contexts, but that was fixed by putting the line Option "TearFree" "true" in /etc/X11/xorg.conf.d/20-intel.conf, which was already there by default in my desktop PC running Linux 24. That seems to fix a problem in the XWindow intel graphics driver for linux. I have not done much testing using windows: I've never liked windows and need it only occasionally. But it may be useful for testing if a suspected hardware fault develops under warranty. I find that shutting down after running Linux gives me the option at next boot to run either linux or windows. But windows is not so generous and after running it I sometimes have to reset the boot options to run linux. (Perhaps I shut down in the wrong way, being unfamiliar with Windows 10) I have never had that problem on previous machines with both windows and linux installed. I assume it has something to do with the UEFI system now used at boot time. -- OVERALL I don't think any other 11.6" Laptop/Notebook computer is available in the UK with comparable or better specifications, including weight and computing power, at or around the price I paid -- which may be out of date now. For a quotation contact www.stonegroup.co.uk The following review is based on about 10 days of use (not full time!). -- STARTING WITH THE WEAK POINTS: The manual seems to have out of date instructions regarding treatment of the battery. All the information I have found warns against repeated artificial recycling of charge, and deliberately draining all charge regularly on a Lithium Ion battery. The instructions recommending regular full drain and recharge are probably a relic of an older model with a nickel-cadmium battery? An earlier draft of this review included: On the other hand the warning in the manual about possibly harmful radiation with wifi on is very good. More manufacturers should do this. However, a colleague informs me that the harmful effects have never been reliably established. Compare https://www.howtogeek.com/234817/dont-worry-wi-fi-isnt-dangerous/ http://www.who.int/peh-emf/publications/facts/fs304/en/ -- TOUCH PAD: I really miss the 3-button touch-pad that was provided on the Dell E6410 laptop, since 2010 my 'workhorse' computer when travelling or giving talks. http://www.cs.bham.ac.uk/~axs/laptop On linux I use the middle button many times every hour (it's the quickest way to paste text on linux, in many contexts). But the Stonebook mini does not have a middle mouse button. On machines with two buttons, the effect of a middle button can be achieved in linux by pressing the two buttons simultaneously. But this machine has a slightly flexible rocker instead of two buttons, so the effect of middle button requires pressing both ends of the rocker. This needs far more effort than pressing two adjacent buttons using one finger. I can partly compensate by attaching a small three button mouse, which the Dell doesn't need. (The mouse increases battery drain by a small amount, as well as requiring additional table space.) I don't find two-finger cursor motion control on the touch pad quite as comfortable on the Stone as on the Dell (with Alps touch pad), but it's possible that I can fix that with software settings, or with more practice. (Sometimes using a separate mouse is not convenient, so I have to use the touch pad.) Two finger scrolling on the touchpad works on both machines, though I seem to have slightly more control on the Dell. -- PAGE HOME/END UP/DOWN BUTTON EMULATION As on many laptops the keyboard does not include space for separate keys for HOME, END, PageUP and PageDown, so they are 'emulated' by using the Fn key in combination with other keys. Despite the (unusual) provision of a second Fn key on the right, I found the need to use two keys uncomfortable for PageUp and PageDown, so instead mapped keys onto the functions I required, as explained below. For example Fn+Left emulates the Home key, and Fn+Right emulates End. Fortunately that has been made slightly more tolerable by provision of a second Fn key on the right. It works quite well with the Left and Right arrow keys for Home and End functions, mainly because I don't use them very often (and in my text editor have alternative shortcuts). In contrast I use PageUp/Down a lot (reading Web pages, PDF and text documents and program files) and miss having separate keys. On the Stonebook mini they are Fn+Up and Fn+Down. But I found it annoying to use the Fn key with Up and Down arrows, especially as I use them very often. So I used the Linux xmodmap function to set the PrtSc and Pause keys in the top row to do PageUp and PageDown, which works perfectly in most contexts. As a Unix/linux user, I often use the Linefeed key, which is not provided on most keyboards nowadays. But since I don't use the AltGr button to the right of the space bar, I set that to be the Linefeed key. Different key codes may be needed on different machines. On my machine the file (which I have named 'keyspecs') read by xmodmap to achieve these settings contains: keycode 108 = Linefeed keycode 107 = Prior keycode 127 = Next The linux 'xev' utility can be used to find the key codes associated with different physical keys. The command to set this all up using xmodmap when my machine goes into graphics mode takes the form (in .xinitrc, by graphical mode startup file). xmodmap keyspecs See also the alternative solution using a wireless mouse described below. -- NO KEYBOARD BACKLIGHT I miss the Dell's backlit keyboard in dim light, but I have a little usb powered LCD lamp that can clip on the top or side of the lid of the Stone. I don't know how its power consumption compares with a backlit keyboard, but it is less convenient. (The extra drain recorded by the Linux battery monitor with the lamp plugged in seems to be about 0.26 amps, but I have not tested thoroughly.) I don't know whether the extra cost of a back-lit keyboard would be higher than the cost of the usb lamp, but it would certainly make the machine more attractive. -- MINOR NIGGLES I don't have fat fingers, but I find the power button very fiddly to press because it is long and very narrow. The length really has no benefits. A slightly shorter wider button would be more ergonomic, from my point of view. Of course the power button is not used often, so this is a trivial point. More importantly, I would prefer not to have to tilt the base up to see the LEDs there. Having them to the right of the power button, with more readable labels would be very much better -- but I don't know the internal constraints. At present the labels, stamped into the casing next to the LEDs, are too small to read and there is no space to increase their size. I would also like to have a CAPS LOCK light. Occasionally Caps Lock gets left on when it should not be, and the result can be unintended text being typed in or some command not working (e.g. a password fails). On windows 10 an obtrusive panel comes up whenever Caps Lock is turned on, which is awful when it was done deliberately. That mechanism is no substitute for a Caps Lock indicator. -- SPEED Unsurprisingly, the machine is slightly slower than the Dell (with Core i5 CPU). Surprisingly it is not *much* slower most of the time, and most of the time I don't notice the speed difference (perhaps partly because my Stone has double the amount of Ram, and I think the hard drives are comparable in speed -- I put a new 1TB WD drive in the Dell a couple of years ago). Managing a display with fewer pixels (1400*900 = 1,260,000 on the Dell and 1366*768 = 1,049,088 on the Stonebook) may also slightly reduce CPU load. For the kind of work I do most of the time, which involves very little 'number crunching' but a lot of reading and writing files (e.g. running Latex to generate PDF, and fetching and displaying internet files) many of the speed constraints are not much affected by CPU speed limits. I suspect there are many laptop users for whom that is true. Ignoring the reduced screen size and reduced maximum number of pixels, Web browsing on the Stone is very much like web browsing on the Dell, apart from the annoyance of a missing middle mouse button, which I use frequently to open a new link in a new tab. Download speed on the Stone (measured by speedtest.net running on google-chrome) is significantly higher than the Dell's download speed, using our VirginMedia 100Mbps cable service. I am not sure about the reliability of such tests. The extra download speed compared with the Dell will be useful for installing new packages and updates, though processing the updates after downloading is slower than on the Dell -- though I have not tried to measure that. I have not encountered intolerable delays installing packages or updates. Compiling the latest version of the ctwm window manager on the Stone, the Dell, and my desktop PC gives the following results: Stonebook Mini: Total elapsed time 25.41 secs (user) (system) (elapsed) 15.387u 6.288s 0:25.41 85.2% 0+0k 63536+12528io 243pf+0w Dell E6410: Total elapsed time 13.63 secs (user) (system) (elapsed) 7.024u 2.552s 0:13.63 70.2% 0+0k 66104+12576io 248pf+0w Desktop PC: Total elapsed time 6.57 seconds. (user) (system) (elapsed) 5.064u 1.439s 0:06.57 98.7% 0+0k 0+12584io 0pf+0w For a small task, the difference between 25.4 seconds and 13.6 seconds may go unnoticed. For bigger tasks the difference will increase. But I don't intend to use the Stone for complex, high CPU tasks. For my purposes (mostly web browsing, text programming, giving presentations, and occasional small amounts of programming), the speed of the machine is fine. Some things take longer to start up than on the Dell, but I have not done systematic comparisons. -- RECORDMYDESKTOP I can run 'recordmydesktop' in full-screen mode, including switching between workspaces with different contents, one of them displaying input from a usb video camera attached, run using the 'cheese' program. [I shall post an example recording here later.] First tests with 'recordmydesktop' to record a full screen presentation switching between linux workspaces (virtual desks) with different content (e.g. text files, images, web pages and a 'cheese' display of my face while talking, worked very well). The fact that the display resolution is only 1366x768 is an advantage for use of recordmydesktop. On screens with more pixels I have to invoke recordmydesktop with tools that restrict the recording to part of the screen, which is a lot more fiddly. -- LCD SCREEN The screen on the Stonebook mini is excellent, with a matte surface and usable brightness in all the conditions I have tried, including outside in moderate sunlight, where I had to set screen brightness to maximum. This seems to be slightly better than my Dell's (2010 vintage) screen. Presumably screen technology has improved in the last seven years. (I don't know whether a display bought seven years ago will have deteriorated.) The screen resolution (1366x768) seems to be standard across all cheaper and smaller laptops though the much more expensive 13.3" Dell XPS-13 provides full HD: 1920 x 1080 pixels (even more on the latest model?) On the basis of my experience since acquiring the Stone machine, more pixels per inch would shrink the display size of all my standard fonts and I would have to use larger fonts, going back to fewer characters per line and lines per visible page. I think that for my intended use (not as a full time machine) this resolution is an acceptable compromise. When needed I can connect an external display with much higher resolution, as reported below. -- 'SNAP SHUT' HINGED LID The lid uses friction hinges and is spring loaded to shut when only slightly open (a gap of about 2cm or less), so that it does not need a catch. Consequently, when lifting the front edge of the lid I have to hold the base down, otherwise it comes up with the lid! That spring-loading has the consequence that it is very easy to shut the lid unintentionally if carrying the machine slightly open, e.g. for use in another room. On my configuration shutting the lid causes the operating system to suspend, which can be useful for saving use of battery. But it may interfere with some pre-prepared demonstrations. -- WIFI and CABLE CONNECTIONS As mentioned above: wifi download speed seems to be very good -- better than the 7 year old Dell. Cable (ethernet) communication works as expected. -- EXTERNAL DISPLAYS I have tested the Stone's VGA and HDMI ports on a projector in our department, and both ports work perfectly. I also tried plugging in a 23" High definition 1920 x 1080 monitor using the VGA port and that worked perfectly for my purposes. (The linux lxrandr tool works like magic with projectors and external monitors.) We have many visitors and some colleagues with lightweight laptops that need adapters for VGA and HDMI. Often this can be a nuisance. Having both built in is a great advantage. -- KEYBOARD Although the small size is slightly inconvenient the keyboard feels good and I am learning to adjust to it. The unusual angles for finger actions seem to produce the illusion that keys are slightly harder to press than on other keyboards, but only when touch-typing with both hands (in my case). As usual on small laptops, the shortage of space for additional keys is compensated for by using the Fn Key to provide extra functionality. This can be very tedious for actions used often. On this keyboard that is somewhat mitigated by having a second Fn key on the right, as discussed above. For a linux user there is further mitigation by re-mapping two of the unused top row keys to PageUp and PageDown (using xmodmap), also explained above. So I don't need to use Fn for those two frequently used keys. As explained above, the keyboard emulates Home and End keys by combinations Fn+Left and F+Right, respectively. The provision of the second Fn key on right, adjacent to the Left and Right arrow keys makes this tolerable. I don't know whether any other 11.6" laptop makes better use of the limited keyboard space. A minor nuisance: The four arrow keys and the second Fn key at the bottom right corner of the keyboard are slightly thinner than the main keys. At first I found that they did not always respond when tapped, and I thought they might have a fault. Eventually I realised that as long as I tap the key on or below its centre it works. If I tap slightly above the center that seems to prevent the electrical contact working. It has been fairly easy to adjust my typing on those keys so that I no longer have the problem, but it could lead some users to report faulty keys.(Added 12 May 2017) -- THE GENERAL CONSTRUCTION SEEMS TO BE VERY GOOD Everything feels very solid and robust. There are four small rubber tipped feet on the base, keeping the air vents clear, and preventing the speakers being muffled. -- REMOVABLE BATTERY Providing a removable battery is a great advantage -- I have heard colleagues complain about laptops with inaccessible batteries that need replacing after a few years. The ability to swap in a spare battery can sometimes also be very useful on long journeys or in long meetings without access to a charger. The spare battery is very much smaller and lighter than the spare battery for the Dell. Removing a battery is easy: two sliders release the catches at either end, as on the Dell. But the Dell's batteries are much larger and heavier. Alternating between two batteries bought with my Dell E6410 seems to have kept both of them highly functional (around 70% capacity) after 7 years -- though that is partly because the machine has external power when used at my desk. Battery life from full charge will depend enormously on a combination of factors including screen brightness, wifi usage, disk usage, and cpu usage. My impression is that with screen close to lowest brightness and no 'heavy' computation, and no attached mouse or other device, the machine could be used for editing and browsing for 7hours or more, but I have not tested that. It easily goes beyond 5 hours. -- CAMERA I tried using both the built in camera and an external Logitek C270 usb camera, which is more flexible for recording lectures and discussions at meetings. Both worked fine, though the Logitek seems to be of higher quality (and of course more bulky). The 'cheese' program (for snapshots and videos) starts up within a few seconds when using only the Stone's built in Webcam. If I plug in the Logitek before running cheese, it takes much longer to start, then allows me to choose between the internal and external cameras. I am fairly certain the machine would struggle if I used the full camera resolution for recording videos (the Dell E6410 also struggles), but I have not tried that on the Stone. I have not yet used this machine with Skype, apart from a brief audio test. I often have audio problems with Skype e.g. on a smart phone, but this machine may be better. -- USB PORTS THE USB ports (one USB3 on left and two USB2 on right) seem to be very tight. This prevents cords being pulled out easily by accident, but I worry about the long term effect of having to push hard to get plugs in. Having the two usb sockets in the middle of the right edge is a disadvantage for a right-handed user when a mouse has been plugged in to one of them: the usb plug on my mouse sticks out about 3cm, and gets in the way of the mouse in situations with a restricted flat surface. At first I solved that by plugging my mouse in on the opposite side, but that uses the only USB3 socket, which I prefer to keep for external memory devices. An alternative solution uses a wireless mouse. Using a wireless mouse instead (Added: 14 May 2017) I bought a wireless mouse to avoid the problem of dealing with the mouse cable. The mouse I bought (Advent AMWLWH16 -- cost £7.50 at PCWorld) uses a tiny wireless dongle with a usb plug that hardly protrudes at all. It also has two extra buttons on the left side, providing extra benefit. Using the 'xev' command I found that they were recognized as Button 8 and Button 9. In order to get them to invoke PageUp and PageDown, I had to install two packages, xbindkeys and xautomation (in Fedora -- other versions of linux may use different names). To use the functionality, create a file .xbindkeysrc by running 'xbindkeys -d' $ xbindkeys -d > ~/.xbindkeysrc This file is used when xbindkeys starts up. After using Xev to find the labels for the extra mouse buttons (8 and 9 in my case) edit .xbindkeys at the end to invoke the 'xte' command, provided by the xautomation package, to create the two new bindings. Each setting requires two lines in the .xbindkeysrc file. I used: "xte 'key Page_Down'" b:8 "xte 'key Page_Up'" b:9 The first line of each xte command specifies the required functionality. The second line specifies the mouse button to invoke it. After editing the file, kill the xbindkeys process if it is already running (killall xbindkeys) then restart it. It will then read your new .xbindkeysrc file. If using .xinitrc to control the start up of graphics on your system, add a line to invoke xbindkeys. Different start up files are likely to be required by different window managers. A side-benefit is that the wireless mouse can then be used during presentations to operate the pointer and the screen and to invoke Next or Previous page. For more information see http://dev-random.net/make-your-own-keybindings-in-linux-using-xbindkeys/ -- MAIN STRENGTHS There does not seem to be any other 11.6" laptop on the market that is so well configured at around this price or lower -- many are Chromebooks with much less file storage and other disadvantages for linux -- e.g. simpler keyboards. Dell has more sophisticated offerings, but at a much higher price (even with less storage than this). Much cheaper consumer-targeted 15 inch laptops are available at lower prices, including a Dell Inspiron provided with linux pre-installed (Ubuntu). But the price seems to go up as machine size goes down. -- PROVISIONAL CONCLUSION I could not find anything comparable in configuration, namely size, weight, RAM, filespace, external ports (USBx3, SD card, VGA, HDMI, Ethernet, separate audio in and out ports), plus high quality screen and exchangeable battery, for a price that was less than twice as high. The machine also works well with linux and has a 5 year on-site warranty. (This may depend on having a site-wide arrangement with Stone.) So I am pleased with the purchase. Stone sales staff were very helpful and patient during the time I was undecided. As far as I can tell this machine fills a niche that is ignored by other manufacturers, and if it were on sale more visibly there could be many more buyers. I studied offerings from several other manufacturers and inspected a variety of examples at a PCWorld in Birmingham. I found nothing that came so close to meeting my needs and constraints.
