Thanks for the videos. It seems to me like they optimized the ability for the touchscreen digititzer to pick up the size of a touch. The soft tip of the pen changes its size depending on the way you hold it and the pressure. Reporting of touch size is actually build in to android. I tested it and different fingers report different sizes. My pinky 1 - 2, forefinger 2 - 4 and thumb 3 - 5. I think that lots of drawing apps don't take advantage of this because the variance is so small when using the same finger. It seems like they where using a customized version of sketchbook that actually takes the touch size into account. I doubt the tip is going to last long and it didn't look like the tip is replacable. Software wise what they did is impressive, but I think I'm going to skip this tablet.
