Oh man. I got a 20.1" Dell 2001FP last week. Thanks to a discount program at Google, this only cost me $600. I brought it home and replaced my very reliable 19" Mitsubishi Diamond Pro 900u. The best part is that I keep it rotated in portrait mode, all the time, at 1280x1024. Finally - a monitor that works like I do! What's nice is that both of my PCs (which share a KVM switch) happily work with the rotated monitor.
Seriously, I'm tempted to buy a second one and have them both rotated. But that's just crazy talk.
