Kindle vs Sony's Book Reader

I have both and my husband and I both prefer the Kindle. The Kindle bookstore is far superior, the Sony does not have a user replaceable battery...it has to be replaced at a Sony Store or mailed in and they cost quite a bit more than the Kindle battery. You will have to buy the charger...it doesn't come with the Sony...for another 30 bucks. The Sony Connect software is pretty clumsy but workable. The Sony page buttons are too tiny while the Kindle's are too large. The Sony cover is not anywhere near foolproof...it has a big plastic snap which can work itself loose from the reader just like the Kindle plastic tab. They both can fall out. They both do an excellent job doing their design purpose, to read books. Over all the Sony has props for style, the Kindle for extra features and ease of battery replacement. The big deal, however, is the book store...the Sony store comes nowhere close to the Amazon selection which seems to grow daily. Sony is not a bookstore, it is a hardware company. Amazon is a bookstore and has been since inception for all their side venture growth.
