So far I haven't had any problems like what I've seen posted on the board. No discolored light spots, no problem keeping the correct time. My only problem has been getting used to how sensitive the touch screen is (and I imagine that will get better as I get used to the reader). I like how you can have your books as a list or the cover in the collections and of course the convenience of the built in light. It does feel a little bit heavier than my Kindle Keyboard but that might be because it is a bit smaller so the parts are in a smaller space.
