looks very interesting: affordable, small enough.
About compatibility issues: http://freedominput.com/mainsite/ind...d=25&Itemid=44 does not yet list the Nokia 770.
Users of other devices seem to have some problems too, and drivers on their site are new (from 2006), so they may still be working on it.
I don't want another driver, I just want something that works out of the box.
