For example, you might have a desktop and a laptop computer and office, and might want your office bookmarks to sync across your office computers only. And similarly, you can setup your home computers to sync across each other only. You will still be able to manage all the bookmarks online for all the computers. This feature even lets you create a small list of bookmarks for quicker access from your mobile devices.
