Due to some fortunate events, I got my hands on a small (miniITX) all-in-one board based on AMD Geode, which you can see in the picture. It is a low-power thing without any coolers (not even passive ones).
My job was to install Linux on it. And I did just that - Debian GNU/Linux with KDE 4.1 beta which is in Debian’s experimental repositories. I hooked the system to my screen so that you can see what it looks like (although it was a bit odd to hook something like this to a 19” screen). It behaves surprisingly well - the system is responsive and works very well (with all fancy Plasma animations)
The ultimate goal is to create an environment for systems that will have the ability to run only a limited set of predefined applications (for example a web browser, mail client and office suite). For this, there will be some changes to the screen you have in the screenshot, but I’ll talk about that a bit later.
