I have a choice between the following Macs: iMac mid-2010 21.5" 3.6GHz duo/8GB/1TB HD + 30" monitor MacPro early-2009 2.66GHz quad/8GB/600GB HD + two 30" monitors MacBook Pro 2011 15" 2.0 Ghz Quad i7/4GB/500GB HD +30" monitor I don't need a laptop often, but occasionally might. The Mac Pro has the benefit of having two 30 inch monitors (I've always been fond of dual monitors). Speed wise, I think the MBP is the faster of the three, but the smaller screen is not as good as having two 30" at my command. So what would you use? Any comments are welcome.
