I've decided to make a career change, and return to school. Since the first couple of semesters are going to be pretty intensely scheduled, I've decided to get a Macbook pro/air (haven't decided), to use while at the college since I likely won't be home very much to use my iMac for schoolwork, which of course has my entire music collection, videos, etc. This will be the first time I've had two computers to worry about that weren't work related (thus not having to worry about music collections etc). My question is this: For those of you who have a laptop as a second computer, how do YOU manage things like music libraries, videos, docs, etc? Do you try to copy the iTunes libraries over to the macbook, and keep them synched somehow? Or not even bother, and just keep them separate? Just looking for opinions on the best way to handle this. Thanks.
