I've had a few folks mention to me how great the Dell 20" display is. I totally love it. Getting to the choice wasn't easy though. I'm a little spoiled with the panel I use at work, and originally thought of getting one of those... of course sanity set in quickly at the thought of spending nearly $3000 on a display that's used primarily for MSN Explorer and the occasional game of Age of Empires. Then I looked at the Apple Cinema Display at the Apple Store. That one was really beautiful. Then I realized that I could buy 3-5 20" Dell Display's for the price of either of these. The decision was clear as day.
The other thing worth pointing out here is that there's a fine line between "simple" and "no longer useful" that Apple crossed. Their display is georgous - hands down. One DVI port meant that I wouldn't be able to use it with my laptop directly! Looking for a KVM switch that works w/ DVI at 1920x1200 and also supports USB input devices yielded offerings over $500 that didn't quite meet my needs either. Dell had the best mix of performance, flexibility, and price - and it's a great product as well!
