I was wonder what you guys think is the fastest way to buy a mac book pro? How does it work at the apple store? Do they only sell the base and top models? What if I want the base, with only a ram upgrade? Will I have to come back another day to pick it up? How does it work? Do I fill something out, like online, like saying if I want Aperture or the apple remote with the package? I know it would be proabley easiest if I were to purchase online, but my parents don't really like giving out their credit card number online. Thanks.
