In my mind the store that you buy the books from is more important then the reader. In fact when a pal of mine told me that he was going to buy an ereader, his question was which reader should I buy. My reply was well which store is the best one for you? We spent the better part of an hour looking at the merits of the different stores such as amazon, kobo and sony. I told him pick th estore first.
The paperwhite is a great reader but how do you like amazon's store?
