I bought one for myself. I have, admittedly, never owned one of the previous Kindles. I have had it a week now, and I am rather happy with it. There are, however, a few things that I wish were different, but it's not a deal breaker.
Pros: I can read on it (the main reason I bought it) with white text on a black background (E-Ink isn't... that particular contrast.). It runs the apps in Amazon's store reasonably well. Video looks pretty good streaming. Even the PC Magazine I read on it looked pretty good.
Cons: It can be "touchy" sometimes and doesn't register button presses. I can't put custom wallpaper on the lock screen. I would like the ability to delete apps I have no intention of using again from "The Cloud", but cannot seem to accomplish this.
