Sure, they expect you to pay $499 - $699 (+$130 for the 3G model) for a WiFi iPad (16/32/64GB), for the ability to do those things on a multi-touch 9.7" slate that you can carry around anywhere.
Splutters !!!!

It's an amazing piece of tech, but even the consumers that buy it would return it if it didn't do anything they wanted.
Its not that amazing on a technical level there is nothing in the IPad that is particularly ground-breaking.

What is amazing is Apple's ability to package lots of tech that already exists into a nicely designed package and convince a few million people that they need one !
