I have had the Kindle since they first came out, and I *love* it. IMO, they're better than the Nook. With the Kindle, you can download a sample (free) of the first chapter of a book to see if you like it. And there are TONS of free/ridiculously cheap books out there, too. It's true the Kindle doesn't have the backlight, but it works to its advantage because I can read comfortably in any light, including direct sun. To me, the Kindle seems to be easier to handle than the Nook because it's easier to type out what book you want and download all from the Kindle. And if you need to, you can change the landscape setting & the font size/type to suit you.
I have a friend who worked in Barnes and Nobles, and she knows quite a bit about the Nook - and she still chose the Kindle. :) With the Kindle, you do have to have an LED light attached to it to read. *shrug* not too bad.
Newspapers, PDF, books from Amazon or from other sites (those sites you can download to your computer, then put in a document file, and then directly download to your Kindle). So... IMO, Kindle beats Nook. The Nook has all these bells and whistles - but it still can't compare to the Kindle. The Kindle has 3G and wi-fi free, and has a very reasonable cost. PLUS, if you want to get cute, you can buy skins to customize your Kindle. :)
