Since I see it in loops on every thread this is my procedure: 0) don't buy iMac now!! ( very important to send apple a clear single that their fans isn't stupid) 1) wait month for mountain lion and pray for speed bump. If 1 happen buy iMac! 2) if 1 doesn't happen either buy something used, or buy mbp. If none of the above: Wait for wwdc 2013 this is probably the time for the iMac redesign.
