I am similarly underwhelmed by Vista. However, it doesn't seem fair to compare Vista to the work of Doug Engelbart. Engelbart was trying to change the world. Vista was only trying to be a compatibility environment for a particular application suite. Don't be fooled by Microsoft's need to market it as something more. It would be better to evaluate XO running on OLPC. I'm not sure it would completely vindicate modern achievements, but it at least has a few new ideas.
