They just lost the ability to sell books and e-books from several major publishers including McMillan due to contracting controversies. This will be resolved I'm sure but how long before that happens I'm not sure. Also be prepared their e-book prices
will be going up due to these contracting controversies.
You can get newspapers and magazines on the Nook too.
Other things to think about on the Nook vs. Kindle debate. The Nook allows you to replace the battery your self - on the Kindle you have to send it away to have this done.
Also, I can store the books in multiple places, not just on the
Amazon server. I have copies of all my purchases stored on my computer, my laptop and my nook.
Plus, this is a biggie, the Nook and Sony handle PDF documents natively, as well as using epub and several other formats - the Kindle doesn't do this you have to send your books away to be converted.
Price-wise you can get the Nook for less than the Kindle. B&N participates in rebate programs like e-bates, etc. and the purchase of a Nook is eligible for these discounts (I bought mine this way and saved $25

). In Amazon's favor tho, if you don't live in one of their distribution states they don't charge you taxes on your Kindle. B&N has not charged me taxes on my e-book purchases.
