Yes, large selection is a killer feature of Amazon. But then you need to be prepared for their pricing policy for the devices. I'm using Pocketbook for couple years but they really not great. Thinking about Kobo
Discussion
I've been searching Kobo's books library.
Obviously they don't have any of my families books, but that aside, they have about 10% of the books in my current collection and they ones are the ones I am least interested in.
So I'm going to have to stay a whore to Amazon for now.
