I've been thinking about upgrading my late 2007 (2ghz alum) 20" iMac for a couple months now. My original thought was to get the base model 24" iMac as a replacement. However, the idea hit me today (after seeing the 24" Cinema display on Apple's refurb site), why not pick that and a Mstand, and just use my 13" 2.53 MBP? I'd probably keep an external keyboard and trackball as well. Here's my situation, I currently share the iMac with my wife and kids (at most they do MS Office, Web, Email, Finances), but we now both have MacBook Pros. We mainly have the iMac for the larger screen. I do a lot of Web design and Photowork (Adobe CS4 stuff). I'm in college studying Educational Technology. Any thoughts?
