I have a different take on the ad. The ad is saying that computer is the obsolete experience, not that the iPad can do everything a computer can do. If Apple truely believed that, they would not have a mac line up.

For a certain demographic of people, I would agree. I continue to push the iPad for my aging parents because it can do what they need to do without my tech support. They don't need all the flexibility of a computer as a general purpose computing device. They just need to browse the web, write emails and watch videos, and the iPad is perfect for them.
