Hi, so I hear that the macbook pros coming out in 2012 will have a redesign to look more like the macbook airs. will that mean these will be less user-configurable? You already can't do RAM upgrades to the Macbook Airs for example. I really don't want to pay a huge apple premium to upgrade RAM and hard drives because I couldn't do it myself via a third party. and two, would you all still buy these super-thin macbook pros if that is the case? I don't see a good reason why I should. Thanks.
