Some week ago I have asked the above question and with the free time during the change of the year I can now answer it an I want to share some experiences: I found the Acer C720 Chromebook with the following technical data: -- 2 GByte RAM (soldered on board, not update-able) -- 2 core CPU, each 1.4 GHz -- display 1366x768, ~11 inch, very nicely support by Xorg VESA driver -- Wifi Atheros AR946x/AR948x, supported by ah(4) -- sound supported by snd_hda(4) -- 16 GByte SSD, can be swapped by, for example, MTS400 M.2 SSD 128GB SATA III, MLC (128 GByte) I will attach a dmesg output; The problem was: 1. It needs take apart the device to unlock the BIOS protection to be able to use a SeaBIOS for legacy boot from SSD or USB; 2. One needs some patches against -HEAD; All this is very good documented by the author of the patches, Michael Gmelin, in his blog: http://blog.grem.de/pages/c720.html Thanks to him for this work and his helping hand during my first steps with this nice device. I think, the patches should be incorporated into SVN, at the moment they are against -HEAD as of January 5th. The keyboard of the C720, in principle a normal PC105, mine with German layout QWERTZ, is a bit tricky: it has - only F-keys from F1 to F10 and they are labeled with symbols for the ChromeOS applications; - no hardware power-off (only by an ACPI key which is situated where F11 would be, i.e. right above the Backspace key, you see the risk :-) ) - no Windows key which could be used as Modifier-key in X11; - no PageUP/DOWN keys - no 'blue Fn' key for additional functions (like audio or brightnes) In his blog Michael documents as well ways to help out of this. It now runs very nicely -HEAD (still booted from an USB stick because I'm waiting for the 128 GByte SSD to swap it). I'm really surprised about the battery: lasts for 6-8 hours. Wow!!!
