Other than the touch screen and the size, what’s the difference of a Tablet PC from Laptops/Notebooks? I’m thinking of getting one.

Specifically, are normal programs not available on a Tablet PC? I saw this demo on the Microsoft site that said it allows you to transfer some of your favorite music from you desktop PC to the Tablet. Does this mean I can’t store my whole library in it? Does a tablet have a DVD-RW or CD-ROM drive?
Is there lower hard drive capacity?

Or is it mostly the same thing?

Hehehe… Thanks in advanced
