According to
an article at Business Insider, the new Nook beats the most recent Kindle.
Personally, I think Consumer Reports is off the mark. After watching all the trouble brick and mortar stores are having I'll stick with Amazon. Plus, Amazon has been a leader in innovating with the Kindle and they are rumored to have some really nice products in the pipeline. Since you are kind of locked in when you buy an eReader I'd be leary about locking into the Nook (although it does run the Amazon reader app so maybe that's not a huge deal). Amazon's customer service is also very good.
One more thing, Amazon's Kindle Store recently passed the one million books mark.
