I have been wondering wether to get a 2.66 17" refurb MBP that is unibody, or a 2.6 non unibody MBP. What's the glass trackpad like? I am also going to upgrade my MB with 6GB RAM and a 500GB 7200RPM HDD. Would the aluminum MBP be better, so I can swap the RAM and the hard drive? Also, how does the MBP handle games, and which one would do gaming better? For those wanting me to look at a 15" MBP, I owned a 17" PowerBook and the weight never seemed to be that much of a bother. I would be getting the last-gen non-unibody MBP with a high-res LED screen.
