I would like to replace my late 2009 iMac, and of course I'm disappointed by the delay in the introduction of the 2012 iMac. Now they say that it is highly unlikely there will be any change others than Ivy Bridge/USB3 which will translate in a small bump in speed. I'm beginning to wonder: would it be a better idea to switch to a MBP Retina with an external display? Obviously it would be more expensive, but I would be able to to shuffle around the MBP. What I don't know for sure is how the performance of the MBP and the iMac compare. I have tried searching results for Geekbench2, and it look like they are fairly close: - MBP Retina 2.6 = 11844 - MBP Retina 2.3 = 10810 - iMac 2011 3.4 = 11648 In addition, using the same benchmark, it looks like the iMac doesn't really get much faster from year to year. Thoughts? Are these numbers representative of real world performance? Any idea how the graphics card performance would compare?
