I would love to have the extra screen real estate with the Dell, but I don't want to end up with a monitor full of issues, on the other hand, the 20" ACD would be gorgeous due to its more accurate color. The only thing I don't like about the ACD is the warranty. The ACD comes standard with a 1 year warranty, any additional warranty costs a little more. The Dell comes standard with a 4 year warranty, so obviously I am covered should anything happen. ...... I think I just answered my own question. Either way, I would appreciate feedback, opinions on either monitor/panel, etc.
