I'm thinking of getting a last rev 17" g5 imac. I'm using crt at the moment and I know it won't be as good but I want some reassurance that it doesn't have any known issues. Is it safe to assume that the current intel imac screens are better than the last rev g5 imac screens, or not? A separate question, how quiet are the last rev g5 imacs, compared to say an emac. Thanks.
