"Good for readers, but not that great =("2.0 starson by kahuna9705
Pros: Good for people who read a lot. Keeps bookshelves clear! Nice, easy-on-the-eyes screen. Good, manageable size.
Cons: No wi-fi. Battery is sealed within the device so you can't replace it yourself once it starts to die. (Nook has a replaceable battery) No over the air updates, meaning you'd have to buy a whole new device if Amazon comes out with better features.
Summary: If you're going to spend $259 on an e-book reader, get yourself a Nook. Much more worth it than Kindle. Sony e-reader has a terrible screen.
Doesn't have as many books available to you. I've had friends return their kindles to buy a nook instead and I don't blame them.
