I've had mine for about 6 months now, and it blows the other e-readers I've had out of the water. I've recharged it maybe 8 times in that 6 months, and since I bus to work, I read it at least an hour to 1.5 hours a day. My biggest problem has been finding good content, since I refuse to support DRM books that I couldn't move to a new device at some point.
(Although I did spend the free $50 they gave us)
I've dropped it a couple of times, onto concrete, so it's a little dinged. The outer casing is metal, so I just used a pair of pliers to fix it. I also feel mine "ghosts" more than it used to, but that could be the temperatures, and, of course, it has the charging indicator bug we got from the last update, which is annoying, but not fatal.
All in all, it's the best device to have around on the 30 hour flights back to my birth country, weighs less than a paperback, and carries enough books and battery life that I don't get left out in the cold.
