They're too big to be the machine I'm looking for, but I've flirted with graphics tablets on and off over the years, and given up on them because of the disconnect between my eyes and hand - e.g. my hand is down over there on the tablet, not drawing on the screen.
I'm now wondering if it would be worth getting something like this purely for graphics work. So battery life and weight probably aren't big issues, efficiency as a drawing tool is the main priority.
Anyone done any work with them and got any thoughts?
