I read somewhere that g5's will never be used in powerbooks, because they are just too hot for such. this is why they went to so much trouble with the cooling system in the g5 desktop.
They might be able to get a G5 into a PB by dropping the speed of the chip, which also allows them to drop the voltage. To a certain extent, the power dissipation is a function of the square of the CPU speed. i.e. 1/2 the speed ~ 1/4 the heat to get rid of.
I imagine even a slowish 64 bit powerbook would have significant advantages over a 32 bit, for quite a few applications anyway.
I don't think that Apple can have any serious problems with cooling. I offered them a CPU cooler I designed which gets 3 times the cooling effect (tested) compared size for size with a conventional laptop cooler. My desktop cooler runs around 0.17°C/W, prototype laptop cooler about 1.6.
They didn't want to sign my non disclosure agreement, and replied that 'They were already working on another technology' (which was a bit hard to fathom, considering they have not seen mine!)
Either that, or they didn't believe my claims, and thought it best to humour me. ;-))))
