Ive decided to finally upgrade my five year old Powerbook G4 to a 15 MacBook Pro. Im pretty much set on all the configurations, except for two: the hard drive and the screen. For the hard drive, I definitely want to upgrade to the 500GB because I need as much space as I can get. Is it worth the extra $50 to get the 7200 rpm version instead of the 5400 rpm? Would there be a significant performance boost? In terms of the screen, what are the main benefits and drawbacks of the glossy display vs. the anti-glare display? Is the anti-glare display worth the extra $50? Ive been happy with my Powerbooks matte display, but since I dont use my laptop outside and dont do intensive graphics work, should I just try the glossy display? Or are the reflections really annoying for those of you who have used it long term? Thanks for the help!
