I noticed a very interesting article on SpyMac regarding the new Intel iMac versus the G4 and G5 Macs. Seems the Intel Core Duo isn't all it's cracked up to be. The thread can be found
here.
Actually, it felt clunky and more like being on a PC the way that it seemed to hesitate for just a moment when doing things. But I was the most disappointed with the render speeds, which were only slightly faster than single processor iMac G5 1.8 Ghz on most test, and half the speed on anything with h264.
