Kindle- what is that?

This looks like an amazing device that just costs too much money. Like the iPhone and Playstation 3, the early adopters of the Kindle will suffer all the problems, growing pains, and high cost associated with a brand new neato product.

I want to love this thing but can't. If it had mobi DRM and native PDF support I would pay the high price. I could then choose from a huge selection from Mobi books or even download Mobi ebooks from my public library, and I could carry all my work documents and other ebooks in PDF.

Anyway, nice gadget for the future.
