I think another important point is that the iPad didn't replace an existing tablet in the users home. It was an entirely new genre of device. No doubt when people bought macs they probably had some kind of computer before it. Most iphone users were just replacing their previous phone, just as the first ipod users were unhappy with their 15 song capacity generic mp3 player. To gain such adoption for a tablet device that people didn't previously knew they needed - is huge! They first convinced the market they needed a tablet and second that the iPad was the right product to meet that need. Incredible!
