I was talking to someone at a local electronics store about Apple laptops and he assured me that there is room inside the MBPs for an additional HD to be added, but I've never heard of anyone doing this. Apple certainly doesn't allow for you to add it when you order from them. Was this guy crazy, or is it actually possible to add a second drive? And if it is possible, could boot camp format it for a Windows OS to go on it so the two boot systems would be completely separate of each other? Thanks in advance!
