Well I got mine and I'm afraid to say I'm not happy with it. I had the previous 24" model before and I absolutely loved it. This new model, at least the one I have, has quite a few negative points though.
Firstly, the glossy screen. I thought it'd be okay but sitting at my desk with the window behind me the reflections make it unusable even although the sun isn't in front of the window. In fact, it's a pretty gloomy day. I closed my curtains and it's manageable now but the reflections are still quite annoying and distracting.
Secondly, either this model has a noisy fan or my fan is faulty. Either way, my iMac is making an annoying sort of thuddy clicking noisy. It's not very loud, but definitely noticeable.
Thirdly, the screen has a definite flicker that is subtle but annoying.
Finally, my unit arrived with a tiny scratch on the glass. I've already called and they've arranged to send out a replacement because of this. However, the other three points make me wonder if I should bother getting another one.
I'm really disappointed with this iMac. I've owned a 20" iMac, the previous 24" iMac, two PowerBooks, a MacBook, and three MacBook Pros, and I can honestly say that this iMac is the worst Mac I've ever received. The fan is noisy, the screen flickers, the extreme glossiness makes reflections a pain and, to top it all, it arrived damaged.
By the way, I do like the design and see it as an improvement. It looks far more professional and matches my MacBook Pro.
