Oh, that's exactly the person I'm looking for! (I'm considering a similar setup) Do you know what software they use/where the touchscreen works best? Thanks a ton!
Not quite how I remembered it. Hopefully it's still useful information. In his words:
---
I was using ArchLinux from within an Android setup using a chroot. The X server ran under Android an was called XSDL, which handles keyboard and allows me to simulate rightclick. I was using Awesome. I bound volume keys to right click and Super (my WM controlling key).
The setup wasn't particularly ergonomic. Problems included the clumsiness and limitation of the X server's controls, the keyboard oriented nature of my Awesome setup, And the general lack of benefit from using a TWM. As far as I was concerned, there was limited merit in having multiple windows active at once when screen space was limited, and other WM with touch in mind would probably work better.

It was around 10 inch, but the resolution was about 1280 or lower, and touch wasn't that accurate.
(1280x800)

Note that this was a while ago, and XSDL has undergone changes.
