Question: How comfortable is the stylus to use? I think it's a bit thin, so I guess it's ok for short periods of time, but if you annotate/use it for a while, does your hand get cramped? My boss has an HP tablet PC, with a really nice Wacom pen, I'm wondering if I should get one like that eventually (if it works on the iLiad, it should, right?), although I know I'll have to take the iLiad stylus out of its case to write anyway.
