I own the Kindle 2. If you ask me to choose again now, I’ll still go for the Kindle instead of the Nook or Sony Reader, because I think the web browsing function is rather important (the Nook and Sony Reader does not have a web browser). The free internet (and now it is free international internet) plus the web browser allow me to look for information whenever I’m in need. It is really a cool feature that cannot be missed. And right now it is free for both the U.S. and many other countries, it is just incredible when you bring it to trip.

I like to use the text-to-speech function on the Kindle too, meaning that I can "read" with my hands and eyes free…

Don’t choose the Sony Reader, it is more difficult and expensive to buy books on it…

And I remember I read this review when I decided to get my Kindle:

Hope it helps
