http://www.newegg.com/Product/Product.aspx?Item=N82E16822136197 i am planning on just ordering this drive, paying 16 dollars less for 70gb of more space for my macbook. (And having a back up incase anything happens) =) First I just wanted to insure compatibility and I want to know whether or not this voids the warranty. Secondly I wanted to know if having a bigger drive is going to affect my batter life and if so how much? I know this is hard to quantify but any kind of input is created. So 1, is it compatible, will it void my warranty, and how much will it affect my batter life? Side note, I dont understand why anyone would buy apple ram and apple hard drives..
