Yea, but the 1000 levels of pressure of a tablet outweigh 100 on a tablet pc.
Ah, yes.
But you can take a Tablet PC with you and use it wherever, whereas with a Tablet, you cannot.
Plus, if the price really didn't matter, he should get a Thinkpad W series laptop.
It actually has a built in Wacom tablet, next to the touchpad.
And two screens.
