Bah. A 30" is vastly superior to two screens. Think about it: with two screens, the valuable screen real-estate right in front of you, where you want the most important things, is instead occupied by 3 inches of BLACK PLASTIC.
I solve that just by having one centered and the other to the side. Soon I'm getting a third screen. You can get 4-5 22" LCDs for the price of one 30".
