About Intel's Core Duo processor...

Great review.

The Core Duo (which, along with its Core Solo brother, is the processor in the new Macs) is a seriously impressive chip. The only significant functionality drawback with the initial versions is a lack of 64-bit support. That's coming in a subsequent update later this year, which Apple will presumably use in their workstation products (as well as future iterations of the MacBook Pro).

Software compatibility issues aside (namely, Adobe's difficulty in porting Photoshop), I think it's safe to say that the Intel transition has been, to date, a remarkable success, with even better things on the horizon.
