I've had an iMac 24" for about a week now - love it. Thinking about getting another one.
The only issue I've had with it was trying to calibrate it. it's way too bright out of the box. The only way to get the brightness down to a level where the monitor can be calibrated correctly is with a third-party app. I picked up a free one called "Shades". Other then that, no issues what so ever. Sorry to hear about all your problems man - maybe you got a lemon...it happens
