So I'm looking to upgrade to a new top-tier iMac in the next month or so (minus the optional extra memory which I will buy myself) But before I do, do you think it would be worth waiting the 6+ months for the next likely iMac update? Have a MacBook Pro which is my workhorse at the moment, and it's fine, I could make do for the next 6 months if the upgrade would be significant enough. But looking around I can't see anything that would suggest the next upgrade (to the top tier iMac at least) would be significant enough me waiting. It's likely there will be some sort form of performance upgrade for that model, fully expecting that, but do you think it will be a DRASTIC upgrade that it would be have been worth me waiting for? It's Apple so it's obviously hard to predict, but any opinions would be appreciated.
