I've been very fortunate to have my Barnes and Noble Nook to use for my classes at UCSB. More than half of my required titles were available as ebooks at a drastically discounted rate. Not only that, but I have been able to convert all types of reading files into epub file types that can be read by the Nook. So, I have a lot of class data on the Nook, which is easier to carry around than my laptop. Plus, I can highlight and take notes on it.
It has been two years since I received the Nook as a birthday gift, and the device is still running strong. I only hope that Barnes and Noble will continue to support this e-reader even with all their new Nook versions that are being released. I don't need something overly fancy and complicated. I want an e-reading device that won't fail me, and the classic Nook performs that feature.
When I get more free time, I will write a detailed review about the Nook. I'm very happy I have this e-reader. I'm still a little sad that I never got to experience the Sony Reader, but everyday I pull out my Nook I'm constantly reminded that this was and still is the best choice.
The only hiccup that prevents me from giving the reader a +5 is the fact that it can be slow to respond when scrolling through the text for highlighting and notes. I did have an occasion this past August when the Nook went dead--no screen, no battery indication, nothing! We never did find out what happened to it, but luckily the Nook was still under the manufacturer's warranty. The customer service people were very friendly, and I received my new Nook within a few days. It was easy to install all my previous settings and books onto the system, and I haven't had any problems since.
