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.
