Kind an interesting thought, especially for the use of turning the glass trackpads into full drawing tablets.

If it works well, I'd totally drop 15 bucks for it.

Anyone used it on the iPhone / iPod touch?

I used someone else's recently, and it works GREAT. Just as good as with a finger, expect much more precise. Definitely get it! :) Feels really solid too.
