These guys know their shit.
http://arstechnica.com/reviews/hardware/imac-coreduo.ars/3All in all, the iMac Core Duo is an impressive machine. If the rest of Apple's product line moves to Intel this smoothly,
the transition should prove to be a big success.
Pros
Speed and performance of Intel-native apps
Rosetta performance
Built-in iSight
Value
Bright, vibrant display
Finally a decent video card (ATI Radeon X1600) on the consumer Mac
True dual display support
Quiet
Cons
Lack of user-serviceability
Short list of Intel-native applications available at launch
No support for shared iTunes playlists in Front Row
