Maybe because of the cheap TN panel used in the current 20" iMac, but I've never liked the look of an external monitor (even ACD) next to an iMac. IMO, it just doesn't look right because of the chin and height differential, even if you get the external monitor to sit at the same height. Too bad another iMac can't be used as a 2nd monitor.

This was the issue that lead to my decision to stick with towers. I like it when the monitors look the same on my desk. :D
