So, I have a few questions about the new Unibody Macbook Pro (15") that I hope experienced users have some feedback on. So, first up is the Battery. I've been scouring the net to find some reliable sources for the battery life expectancy of these Macbook Pro's. However, on reliable sites that do "real life" tests and stress tests, I learn that the MBPro's really only have about 2 - 2.5 hours of battery life. However, through forums such as this or through my friends that have Macbook Pros, they claim that obtaining a 4-hour battery life is quite often seen in their daily use. Now, I understand that battery does eventually die down, but what is the REAL battery life for the Macbook Pros? I mean, on average = average usage, what do you all get for Battery life? I'd like to know what applications you consider average and therefore what your Battery life turns out to be. Second, I've been wondering about the Unibody build for the Macbook series. I know how it works and whatnot, and I've seen discussions about aluminum being malleable instead of "crackable" and such. However, I've also seen amazing people who toss their notebooks far and wide to achieve only a ben in the aluminum. So is the aluminum stronger (not in feel, but in actuality)? As in, it might be malleable now, but does the malleability kick in from small drops or for stronger hits? I've seen people complain that plastic only cracks from drops while the aluminum bends like crazy, but the argument is that plastic cracks more easily and it requires a much stronger drop to bend the aluminum. Any personal experiences out there to verify the actually drop-ability of the Macbook Pro?
