Hi, I am wondering about Apple's decision to use Aluminum on their laptops. Aluminum is a heat conductor (it transmites heat), and by doing so, it is not such a good idea for a laptop where you really wanna keep things cool. It seems evidant now that this might have been a mistake, due to all the complaints that the Macbook Pro is really REALLY hot, some go as far as saying that at certain points it is hard to touch it. And it makes sense. a hotter CPU (believe it or not, since it is still much more powerful than the G4), a hotter GPU, add the 7200RPM hard drive and a very very slim form factor to the equation, and you've got yourself an oven. solutions from other companies included high quality plastic (HP), magnesium alloy (Dell) and Carbon Fiber (Acer, Asus). All those materials are not heat conductors. I am hoping for use of better materials for the next generation of laptops from Apple, ones that will match their new power-hungry platrorm. From Wikipedia: "Aluminium is a good heat conductor which is why it is used to make saucepans." Oded S.
