Looking for a 2nd monitor I'd like to hook up to my 27" iMac when I get it (Jan 2-8 ship date). I've got these 2 in mind: 1. Dell UltraSharp U2412M. I'd probably use this in portrait mode next to the iMac. 2. Viewsonic VX2453MH-LED. I would definitely take the stand off and use the backstand option (I'd think it'd look nice next to the iMac). Any other suggestions?
