This reinforces what I've been telling people for the last month or so - the iPad is disruptive to the PC. Maybe it isn't as good as a PC in a lot of situations, but it provides sufficient functionality and speed that people will choose it for its ease of use and portability. And, in a few generations, you will be able to do anything you can on all but the highest-end PCs.

Sure, most people will still use PCs at work, but at home, you will just whip out your tablet.
