Funny you say that. I have yet to buy a Kindle. Do I want one? Sure, but you know what? It can barely read PDFs. I hear the latest one has a built in PDF reader but even that doesnt do so hot. Not only that, it isnt in color.
The Nook, however, is in color and you can let a friend 'borrow' a book for up to three weeks I think it was. Thats pretty daggone cool, but from reviews that didnt get it right either.
Bottom line, Im sticking with my EBook reader on my Droid, iTouch and laptop. They apparently cant get it through their head to make an EBook reader that can read EVERY format and process color. Until then, Im not interested.
