I'm considering one of the iMacs, but....
I have a top-of-the-line previous gen iMac with a Core i7. Someone wants to buy it from me. I'm considering selling it and buying one of the latest, top-of-the-line iMacs. However, that would still cost me a little out-of-pocket expenses.
I'm still not sure the performance difference would be worth a few hundred bucks. The i3's are a big boost from the Core 2 Duos, but the i7 is still the i7. The graphics cards in the latest iMacs are more powerful, but other than that I don't see much reason to switch. Moving to an SSD will definitely speed the boot process up and some apps will feel a little swifter, but they're still way too expensive in my opinion.
If there was USB 3.0 support, I might consider upgrading. If Blu-ray playback was part of the upgrade, baby, I'd be there. But, right now, I just haven't convinced myself to make the move.
