If (only if) I decide to sync my bookmarks and etc between devices how are they presented? I have different info or each device. Do they all meld together into one list? Are there separate folders displaying each device content? Are there duplicates listed from all the devices? I've wasted a bit of time searching here for this but don't find sufficient detail and am not sure I want to proceed.. What if I don't like the result, can I go back?. Basically, what are the nuances of syncing info?? Thanks
