I own the international version of the Kindle 2. I got in for Christmas 2009, and I use it almost every day. I'm a student and I try to get as many of my text books as possible on the Kindle.
The E Ink display is great. It looks like paper. I wouldn't want to read on a laptop or my iPhone for extended periods of time because the screen is bright and wear on my eyes after a while.
It also wins over computers and smart phones for the style of reading that I want to do when I'm using it, if I'm using a computer, I'm going to skip around and not read the text, and the display on the phone is too small to get much reading done. The page turning style of the Kindle is like a real book and allows me to linearly go through a text and not get distracted by the other functionality of a computer.
The Kindle store is pretty cool. I'm a poor student, so I don't buy much on it, but I would love to get some of the periodicals and there are a lot of public domain books that I've been meaning to get around to that are available for free on the Kindle.
The battery life is fine. It goes for days without needing a recharge, but I wouldn't mind charging it daily. I already charge my phone and netbook everynight.
The Kindle 2 with firmware version 2.3 is great. It has native support for pdfs, and some documents I need for school, and the freely distributed books I've found were in pdf. I originally wanted the Kindle DX for pdf support, but the 2 does everything I need it to for less money and a smaller device to carry around.
The Kindle is a pretty good device. I don't really have any reservations about it, but I am worried about keeping my library if I move to another platform. The Apple iPad is set to come out soon and it looks like it's going to be pushing ebooks and the Barnes and Noble nook and other devices currently aren't compatible with Amazon drm and vice versa. I love the Kindle as a device, but I'm afraid that I locked myself into Amazon for the rest of life.
