I guess there isn't much more I could say other than I own the Apple CinemaDisplay 30" LCD screen, and I am a heavy duty Microsoft/.NET developer. I work entirely in Windows 7 on my custom-build PC (not a Mac), and this screen has been great. I purchased it quite a number of years ago, and it is still running strong.

If I was in the market more recently, I would definitely go for an LED LCD screen, rather than a CCFL LCD screen. LED screens, particularly those with a clear/glossy screen, offer a much wider gamut, more accurate color rendition, and broader coverage of the AdobeRGB and NTSC gamuts than other screens. There are several manufacturers who make LED computer screens these days, including Eizo with their ColorEdge screens, LaCie with their new 730 model (one of the best photo editing screens on the market with the broadest gamut I've ever seen...my next screen if the Apple ever dies), as well as more well-known brands such as NEC (I'm having a hard time finding professional grade LED monitors from NEC right now), Apple, etc.

If you want a high quality, wide gamut screen that is designed for a photo editing workflow, I highly recommend looking into LED screens, particularly professional grade ones. NEC and Apple will have them at more reasonable prices, but with narrower gamuts than true professional grade LED screens. If you want the top of the line, with the widest gamut currently available, look no further than the LaCie 730. It covers 123% of the AdobeRGB color gamut, which is ideal for photographic editing. It is not quite as physically appealing as the Apple CinemaDisplay, but color-rendition-wise, it is fantastic.
