I agree, there are other LCDs to be had that are also pretty nice. Though Apple's is pretty sweet... Of course, a major (IMO) drawback is the inability to adjust hardware settings (brightness, contrast, position, etc) via a PC. These controls are enabled through the Mac OS X and therefore, require a Mac to make the changes. If you like the default settings you are fine. Want to change anything, and you are stuck. Just my .02 cents. If you are buying one of these displays, you'll need all the help you can get.
