I have a MBA 1.8/128ssd and an ACD monitor - GREAT set up. I have an HP Desktop that Ive decided to replace. It was getting used for downloading torrents, email, surfing, some photo editing and also a server ... Considering an: - 24" iMac, 2.9ghz, Nvidia GT 120 or - 24" iMac, 3.0ghz, Nvidia GT 130 or - Mac Mini and share the ACD with my MBA I thought about ordering the mini with the maximum spec's. That sounds practical but for not a lot more money than an iMac can be had giving me the extra monitor and lot's more power. If money wasn't the concern what would you buy? Anyone work with dual 24" monitors, not sure how the ACD would look with the iMac display, would have to use a stand to ensure they where the same height I suppose.
