Check out the reviews
The last or the one before Macworld had a monitor test. The tested a hole different kind of monitors. The apple 22" was one of them. Only the LaCie was slightly better and one other -don't know the brand- was better form all of them. Sure, the back might be a little bit off because the are based on white but more or less the 22' is really great. I will get one after the next mac expo now. If you need a calibrated monitor buy one extra and just check it on this one if you really need a proof.
Cheers
