Here's an interesting video with a 'dagi' stylus on the iPad. What's interesting about this video, is that the girl is using a modified bike glove to prevent unwanted input!

This is a novel approach to preventing unwanted input.

As an aside: the drawing app (Sketchbook Pro) is amazingly cool and a 9.7" screen is very functional for this usage! In any case, here's hoping Autodesk has an android port in the works for the barrage of Tablets on the way!

I'm really curious now to see the sensitivity and speed of the Tab's input.
