Let's try. a) If you are looking for an iPad replacement, then I am afraid the answer is *no*: iOS, for all it can suck, is made for touch. Linux is not. b) Your first problem is to find working hardware, and it depends on what you want to do. Basic touch works for example on my Thinkpad X220t which has an integrated Wacom digitizer. I've been trying to use it to annotate pdfs and it kind of works, but there are no sublimities like not registering finger touch when you're using the pen. I've managed to make a Chuwi Tablet work under Linux after recompiling the goodix module. The tablet has a (good) Atom chip and it does work with Gnome 3, albeit not as snappy as Windows 10. I've installed trinity yesterday and I am now playing with the possibilities to make it "touchable" but KDE 3 was clearly not created for that. I'll post more when I find out. So you have to find a tablet that has enough power to run a GUI *and* will boot Linux *and* has a supported digitizer. There are not so bad Chinese tablets around (Chuwi, Teclast and others). Chuwi claims "Ubuntu support", which is right as there is a BIOS setting to boot Linux. However they changed the digitizer during production which is why the kernel does not find it (you must change the model number in the goodix.o source and recompile). Digitizer support seems to stop sometimes (maybe compiling the module in the kernel would help?) c) When the digitizer works, multi-touch support seems less developed than under Windows or Android (I never really used iOS but I understand it should work). Auto-rotation is another thing that does not work. When it comes to writing, Goodix is just unusable (not only with Linux). If you want to *write* you need a much better (and expensive) digitizer. With Linux I would look for a Wacom. I have bought a second hand Sony Tap11 (waiting for it) that is supposed to run Linux and have a Wacom device. More about that around the end of the month I hope. I am also looking for a second hand Microsoft Surface Pro. Version 2 seems likely to run Linux and have Wacom hardware. d) Last thing: some recent devices (my Chuwi Hi13 for instance) have 3K screens (3000x2000) that look gorgeous but require UI scaling. Windows 10 does this without asking, Gnome 3 is relatively easy. Trinity has options but I am testing what works. Basically the UI should be vectorial to be able to scale easily and Trinity had bitmap elements, so it gets quite ugly (128 pixel icons on a HiD screen...) I would say that for light use (I mostly need a tablet to control a presentation tool), unfortunately, for the moment, Windows 10 is the best. You get itchy every time you have to work with the OS, but the GUI is actually not so bad. I hope I have better news in the next weeks but I fail to see anyone really trying to bring Linux on tablets for the moment (Ubuntu seems to have abandoned, KDE is way too heavy, Gnome is barely usable, the lighter DE's don't care (or can't).

Hardware works decently well, only 3 things are broken (only 3 stages of brightness, backlight cannot be turned off, two of the case buttons (P1+P2) have the same scancode). UEFI is an abomination, I would never use these devices for myself. Device comes with with windows10, which is not usable at all. What's worse: these "new" Intel atom CPUs are not faster than a EEEPC800 (on windows, too). Only OpenGL is really OK :-) What I have seen, the hardware of intel based tablets is about the same over all brands, which means there is not much power in it. As it comes to TDE, it works very nice on these devices. Nik -- Please do not email me anything that you are not comfortable also sharing with the NSA, CIA ...

Hi, You are not quite right. I use an all in one computer with a touch screen with Trinity. It's quite good, because all of the screen elements (icons, control panel, window frames) could be enlarged enormous, so the can be used with fingers. As screen keyboard I use xkeyboard which integrates also very well. Most problems make websites which work with a fixed size layout. Ok, it is not a real workstation for day by day work.

Fascinating -- I'd go for one forthwith were my entire experimental budget not tied up in the Planet Computers Gemini, which I am to receive Real Soon Now. As we wait for it to ship, the rumors are getting crazier and crazier; the one thing that I know it lacks (that I wish it had) is some sort of Trackpoint-like pointer control; instead, it's pure touchscreen, which means I'll be developing new skills in keyboard navigation (thanks in part to answers gotten here). If it doesn't work out as I hope, I'll be in the market for the Toshiba. -- dep The shortest distance between you and playing great acoustic guitar: the great new instructional DVDs from Marjorie Thompson, available at www.MarjorieThompson.com
