Certainly less than the alu MBP's.
My alu came dented out from the factory. There was no way to set it straight on the desk.
The new 13" I got looks way more solid.
from 2001 - 03 they were made of titanium actually.
I've seen too many forums posts with pictures to believe otherwise. Its great that yours survived but one post does little to refute the higher volume of others complaining that their MBP (MB) is dentedIt does not dent easy. People who think it does are reading too much into internet rumor.
but since then aluminum-and all MBPs have been aluminum.
Anyways, to add my two cents: Ive owned an aluminum G4, aluminum MBP, and an aluminum MBP unibody. The first two dented like crazy while I was trying my damnedest to keep them in good shape. That being said that unibody doesn't dent nearly as easily... just like some have said.
