I just saw the benchmarks of the new 21.5" iMac. Is it me or are you even more impressed with the 15 rMBP? I know Geekbench is to be taken lightly but it's an equal ground measurement and on my system (2.7, 16GB, 512GB) I get a score of 12383. VS the top end 21.5 iMac of 12447. Opinions. rMBP impressive or top of the line 21.5 iMac not so much?
