But the Mac 27 has fewer pixels and is smaller than this beast. I have a U3011 and think it's great. It's a real pain to use with a Mac, however. Be ready for a LOT of frustration.

For $850 one can get a Mac 27 inch refurbished from the store at Apple. It does require a video card with DisplayPort out.
