Quote from kids
I think the nook from Barnes and Noble is preferable over the Kindle as it supports most of the common eBook formats (rather than just Kindle's proprietary format).
My apologies for a slight thread hijack!
I'm a nursing student and I've got both a Nook Color and a Kindle w/3G. While the nerd in me likes the touchscreen NC better, the Kindle is lighter, has the free 3G (I've used that a lot in my last clinical rotation to look up stuff on the Internet), and Amazon
has a much better
return policy for books. I mention that last part because I've been looking for a good drug guide and bought one from Amazon that, while the book version is very good, the Kindle version not so much. I returned it for full credit the next day. At B&N, once you buy, it's yours w/no ability to return it. With B&N I would have been out the $30 (or at least not able to use the book like I needed) but with Amazon I got my money back.
The PDF reader's navigation in the Kindle is not as flexible as the one in the NC but you can e-mail documents (*.doc and PDFs) to the Kindle and convert them to the Kindle's format if you wish. One really neat thing about the Kindle's format is that the Kindle can read to you. (Retention goes up markedly for what we both see and hear!)
