One thing I think is being overlooked is that there has been no mention so far of multi-user support on the iPad. It seems like it would be a device that could easily be shared amongst multiple people in a household, but there would be no clear way for each particular user to have their own unique experience. Say you didn't want your iPad experience to be cluttered with games, and you want to keep little Johnny from deleting your iWork files, how would you do this without buying two?
