I got my wife a Kindle 3 and she loved it so much that I got one for my mom and myself. I find I read much faster on my kindle than I do on a normal book. In fact the first ten days I read three novels.
I use the iPhone app a lot at work so I don't have to tote my Kindle to work and sync the last page so I can pick it up again at home. It's a great device!
I love the zombie fiction genre and there's quite a lot of zombie fic stories available for 2.99 or less
