I've had a Kindle for over 2 years and love it. I can take it with me on trips, and other then take off and landing, can use it anywhere, any time I want. I can carry 100+ (many free!) books with me at a time, and download new ones almost anywhere.

I'll frequently browse Amazon's top 100 free books on my computer, and send a lot of them to my Kindle. Turn the wireless on on the Kindle, a voila - more books!

However, you don't need a Kindle to read Kindle books. Check out this link: http://www.amazon.com/gp/feature.htm...d_i=1000426311

Sorry I don't have any information on the Nook, comparisons, etc. Hope this helps!
