"Vista improves on the handwriting recognition of XP significantly, and it learns when you correct the recognition - you don’t sit around training the PC. It also introduces pen flicks - gestures that let you copy, paste, delete, scroll or do any eight things you fancy by flicking the pen up, down, sideways and to the four quarters. That only works with an active pen."

We have an active pen with our OQO but frankly we just don't tend to use it. Part of the reason is that there is no docking port for it, either on the OQO itself nor on the hard cover carry case. Also, you do get used to the built in key-pad.
