The Core 2 Duos have hit the new iMacs. Shouldn’t be too long before the macbooks get the hit too. I’d speculate the minis won’t see the upgrade for a while, especially the entry level model, since they should be a little less if they want to compete with Dell.

The 24″ iMac is looks pretty sweet but a little pricey compared to a Mac Pro (entry-level) and a dell monitor.
