So I was wondering.. I'm planning on buying a MacBook Pro soon, but I'd really like to get a Seagate Momentus XT Hybrid drive for it.. But I really don't want to void my warranty. Can you have the Apple Genius' put in a third party HDD for you so it doesn't void the warranty? Especially if it's when you buy it? I don't wanna void my warranty right off the bat.. But I'm not too keen with apples' HDD upgrade options. Any suggestions?
