I use an ACD 23" (which I got nearly half price 9 months ago) with my 3 1/2 year old Win XP laptop. I was thinking of replacing it with a MacBook Pro which should give me more options combining laptop screen with external display. However, I have begun to think I wuld better value by getting an IMac 24" with RAM/HD specced for photo processing and keeping my Win laptop for the rare occasions I need to take a laptop out. (which are not to do with image processing). Wonder what to do with ACD however - will the IMac run that in dual monitor mode - does it have a DVI out?
