I'm buying my first Mac, and I'd like to save a few bucks on the display. I've read good things about the Dell 2005FPW, for example, which can be had for under $600 depending on which specials they're running that week/day/hour. Is the 20" Cinema Display that much ($400) better? They're both 20" wide aspect. Are there other displays I should look at? The widescreen part isn't the deciding factor, but I use it as a point of reference vs. the Apple display.
