One who knows about monitor will definitely heads for IPS (In-Plane Switching) panel, example the
Dell U2410 LCD,
Apple Cinema Display or
HP LP2475w. With bare eye alone, you'll able to notice how different this type of monitor will be compared with normal consumer TN panel such as Dell ST2410, those Samsung, Viewsonic, etc.

If I recalled correctly, Dell 2707WFP is IPS panel too

Mac don't brag about spec. Mac can do good in almost a lot of things especially when it comes to editing photo or video. We don't say spec matters nor Mac is designed for being so, but Mac talks about features and why having one could be great. Please don't get me wrong, I'm yet a Mac user but I do know how powerful a Mac can be and why people going crazy for Apple's products.
When you own a Mac, remember this.
"Don't try to think how to do it in a Mac, but instead think of how to do it with a Mac". We don't transport our Windows knowledge to utilize a Mac
