I am going from a Late 2007 MacBook (White) to a Aluminum MacBook. I would like to know if it would be possible for me to just take the hard drive out of my existing White MacBook and put it into the Aluminum MacBook. This would simplify the process of switching my stuff over and maintain my 320 GB capacity. Also, on a side note, if I have an OEM version of Windows XP on my existing HD, will that work fine if I switch the hard drives? I'm looking for an all-inclusive offer that would detail any and all problems I might face. Thank you, and I'm sure I'll get a proper answer.
