So, I am finally making the jump from PC to a MacBook Pro in the coming weeks. I was checking out the apple store and noticed that the only MBP that offers a 7200 rpm hard drive is the 17 inch model. I am concerned that a 17in MBP might be too big for me. I contacted apple and they said that they offered this option early in the 15in MBP run but discontinued it. 1. Has anyone here attempted to update a 15in MBP with at 7200rpm drive? I checked out the tutorial on the iFixit page and the replacement seems easy enough. Does anyone know if there are any size/ heat issues with the faster drive? 2. Should i even be concerned about the size of the 17in MBP? I am a college student so I move around quite a bit, however I do a lot of web editing, audio recording and photo editing. I really like having a larger screen but don't want the computer to be too cumbersome. Any comments from 17in MBP owners? Thanks in advance.
