It would be great if he could draw a straight line without stuttering. We then tried it on an iPad with the same results. The stylus seems to change randomly from the equivalent of a left click and a right click (maybe? maybe a middle click?), causing the app to get confused as to whether you're writing, undoing, or just swiping through the options. Anyway, two different platforms, same result - then the stylus almost works for basic pointing, but not like a real stylus.
