Artists, yes. Everyone else? I just don't know if handwriting recognition software has evolved enough yet for it to be [highly] error-free, responsive, and most of all, truly usable. Until then, it would be an expensive iphone...

The usability difference that I see between the iPhone and a notebook computer are these:
1) the ability to enter alot of data
2) pixel precision computing with a mouse

So unless a tablet (without a keyboard and mouse) can reconcile this gap effectively, I can't see it being successful.

I wouldn't be surprised if Apple were doing alot of R&D on a tablet, but I don't think we'll see one soon (within the next year).

Sorry if I've busted anyone's bubble!
