Tell me why you like or dislike each one! I want to get DH an e-reader for Christmas and I'm hoping to nab one on sale on Cyber Monday. I'll probably stick to a simple e-reader and nothing fancy like a Kindle Fire (we already have an iPad).

In the little bit of research I've done, there are things I like about each:

The Kindle has more titles available, but I've heard you have to pay to remove ads (what!?). Also, DHs mom and dad have Nooks and I know you can "lend" books to other Nook users and they have similar tastes in books.
