Listening to Steve Jobs talk about the iPad at the media event....
The bare minimum starts at $499 and if you want 3G built in radio for cell/data connectivity it costs another $130 so you're looking at $629 for a bigger version of the iPhone. That's it. Nothing more, nothing less.
I think I'll stick with the iPhone and my 13" MacBook!
Apple could have done a much better job of this considering the competition. I'm not getting one as is...especially with the AT&T 3G network. Ouch!
