To me, latency is by far the most important issue here, and I don't see any mention of it on the page. Compared to my Wacom tablet, touch input is just too laggy to use in anything but the most basic drawing and note-taking tasks; is Bluetooth better or worse? (Judging by my existing BT devices, I'm gonna have to guess "worse".)
