I've been working with a MBP early 2008 (pre-unibody) for a while now. It's starting to show signs of a good deal of wear, so I'm looking to buy another computer soon. I'm interested in getting myself an iMac, at least when the next generation comes out (which should be soon since it's been a long time since the last generation was introduced, almost a year I think). I use dropbox to sync all my university files between my MBP, iPad, and PC. But I have a good number of Garageband projects (as well as a number of other documents, etc.) that I'd like to be able to sync between Macs when I get the new iMac. What's the best way to do this? Does iCloud sync garageband files as part of the "documents and data" option? What about the "documents" folder? Can I tell iCloud to sync other folders that I need to leave in place (i.e., that I can't move into the dropbox folder or that would be too big for dropbox, as the garageband files might be)?
