Hi I wonder, where the differences between the SB and IB-processor from intel are. The IB are likely coming out early 2012, right? So Apple is going to replace SB with IB then? I heard that IB is based on a new 22nm technology. Can you please tell me something about the Speed-improvement compared with SB? Is the step from the processors now to SB bigger, than the step from SB to IB? Where are the benefits (maybe to be used for smaller products?). Do you recommend waiting for the Ivy-Bridge-processor-refresh of the iMacs next year instead of buying a new iMac now (in addition I heard rumors, that the next iMac-refresh is going to be a major-update). We changed from Windows on Mac this year and we're blown away, Macs work just perfect, to be honest, the new iMac is a beast !!! Now my parents are thinking about buying a Mac too. (I allready told them that a Mac is in every case a good choice ) Thanks for your answers.
