The 15" MacBook Pro that I've played with is definitely too hot to  
place in your lap unless it's doing nothing but idling.

Of course it does.  But Intel has a different concept of "normal"  
operating temperatures vs what we're used to in the PowerPC world.   
For instance, the mobile Celeron and Celeron-M run at 100°C and pull  
a whopping 26.3 - 37.7 core amps @ 1.3 VDC!

Of course, the Core Duo is an "improvement", but it's still not close  
to the PowerPC world for efficiency.

And BTW - if you look at the heat removal system in the MacBook Pro  
(similar to Intel-powered Thinkpads), that same system would very  
adequately cool a dual-core G5 processor as well.  The dual-core  
PowerPC 970 MP's (with built-in virtualization) are available in IBM  
Blade servers running linux, and they're renowned for low power  
consumption, low heat dissipation, and they're air-cooled (not liquid  
cooled aka the PowerMac).
