Looks to me the source of the heat problem is the induction nature of aluminum along with the fact that the hard drive is right beneath the palm rest is the cause of the heat issues (my friend's on all day definitely exhibits this behavior, while my iBook--in which i have no idea where the hard drive is, does not).
So maybe this new machine will or will not have issues...
thoughts?
this is probably the least known about of all the books!
