Hi everyone! I'm sure this might been asked before so please excuse me for asking again. I have just seen the new Macbooks at the Apple Store and I fell in love so to speak. I am eyeing myself on the lowest end 2.0 version. I have a previous model 15" MacBook Pro Core2Duo 2.16 which is fast enough for my applications (Blu-ray, HD-DVD movie playing under Vista, Garageband, Final Cut Express...). Just opened it up and upgraded the hard drive to a Seagate 320gig 7200 beast...and man, is it ever faster. My problem is, as with others in this forum, the MBP 15" can get too heavy to carry around. I have been lugging it everyday now and I'm beginning to feel the strain. I don't like to retire my MBP anytime soon, it's still a poweful beast. I plan of using it a home entirely as my main Mac. Will the low end MacBook aluminum be a good portable alternative as far as power is concerned? I also play Spore occassionaly. I also plan of upgrading it's hard drive to the same 320 giger as my MBP. I can care less about the illuminated keyboard of the higher end MB. Can I pick someone's brain on this? Greatly appreciated.
