Several people have asked about the inking experience on the Shift in comments on my previous posts about the Shift. 1, 2, 3 & 4
The Shift has many good points. Inking is not one of them. Like many UMPCs the Shift is fairly uncomfortable to write on. If you do try it out you will find that you need to hold you hand up off the screen, otherwise the ink will jump between the point of the stylus and the heel of your palm. This is because the Shift does not have any palm rejection technology.
In short, the Shift offers a much better touch experience than the inking experience.
