Basically useless. I don't see Apple doing this until earliest 2009.

There's no way the extra performance will be worth the sacrifice in battery life and heat...
 
Maybe useful if your cooker's on the blink, as your MBP could double up as hot plate for those bacon & eggs
 
It won't happen, dream on. look at hot they are now it would burn the hell out of ya The Core 2 Duo is already a pretty hot processor imagine a Core 2 Quad. Intel told people that this was to be a gaming or multimedia laptop processor not for an inch thick laptop. This maybe a good candidate however for the 24" Extreme iMac, but not the pro for at least a few years.
 
Quad core was developed for desktop machines, the cramped quarters of a laptop aren't fitting to a quad core.
