I have the Pogo stylus. The problem with it, or rather with ArtStudio, Sketchpad, Brushes and all the stylus note-taking apps is the same: you cannot rest your hand on the screen. It registers touches from the hand instead of the stylus. That makes all of these apps pretty much useless as far as I am concerned: it is quite inconvenient to draw or write using these applications, even though some of them are extremely impressive otherwise. This, frankly, boggles my mind - granted the screen sensor API is closed, but is it not possible to do velocity distribution thresholding on different touch events, or maybe something more sophisticated, a Kalman filter or something, to distinguish these touches and ignore the 'stationary' ones?
