I have a 15" MBP with 256ssd installed and a 13" MBP with a 250gb 5400 drive. I prefer to use the 13" as my main computer and want to take the 256ssd drive from the 15" and put it in the 13". Then take the 250gb drive from the 13" and put it in the 15" How hard is this to do? I've not done something like this before. Since I'm swapping an ssd with a regular hd is it as easy as following the instructions on this forum, remove the screws and swap the drives? After that's done I'll need to overwrite the 15" software and load the OS and drivers for the 13" on to the ssd drive. Is that as simple as taking the restore disk for the 13" put it in the drive and reinstall the OS? Or, should I just take it to the local authorized Apple Dealer and have them do it? (We don't have an Apple store nearby. Thanks in advance for any help/tips.
