DH and I have Kindles, and as he was a semi-nonreader- he is now reading like crazy! We both really enjoy them, and the advantage for me is that I can bring a decent size library with me wherever I go without taking up tons of luggage space.
I like the feel of it better (Kindle 2). It has rounded corners, and the buttons are easy to use. I'm not a tekkie- but I really enjoy slipping it into my bag and being able to pull it out anywhere.
We were invited to a special church program at a friend's church, and had to get there an hour early. So while we were waiting for the program to start, we pulled out our Kindles and read while we waited. We didn't disturb anyone, got quite a few questions about them and did some demonstrations- and might have sold a few!
I haven't spent much on books- I look for classics and books that are free. I did just purchase an 8 book set for $24.50 which works out to $3 or so per book. Better price than the $7.95 or so that I used to spend on paperbacks.....
HTH...
