Dude, relax. There's nothing magical about Macbooks that allows them to use only Apple-approved hard drives. And you can read plenty of reviews for Scorpio, WD, or any other manufacturer online, like at Newegg. There isn't a single "best" drive for an MB; it's basically a question of what you're looking for in a drive, and how much you're willing to pay for it. As long as you aren't buying a killer Seagate 7.01, your computer should be fine.
