My wife bought me on for my last Birthday. I who read maybe 2 books a year while on vacation have read 7 or 8 since last November. We have read some books silmultaneously. We love ours. Very easy to use.
Ever try to read a book while you are having lunch ? With the kindle lay it flat on a taqble and tap it with one finger to page advance.
I also have an iPod touch and using the Amazon Kindle app I can read the same book on my iPod and sync the last page read between the two devices. Very cool.
