will be getting a new mbp soon, and my wife will use my macbook. As its more portable, its likely we'll take the MB with us if we need a computer when out and about, and also for lazy sofa browsing. So I'd like to have my bookmarks and email etc on both, but not all of it. and I probably don't want any of hers. Can I set up certain bookmark folders to sync and not others? How about grouping contacts so some are on my MBP, some on her MB and some on both?
