IE tabs, bookmarks, and passwords sync between my pc, Surface, and phone. Click the tab button and at the top left of the tabs, there is a dropdown to choose which machine you want to see tabs open.
Also, with a MS acct. if you have it set, my Lumia 920 on WP 8.1 is synced to Onedrive so I can restore or start a new phone and all my icon placements and apps are restored in a few minutes.
Thanks for the info. I hadn't actually noticed a way to do it. While that isn't exactly what I'd prefer, it is handy enough. I now see how to do it in the 'modernUI' version of IE, but haven't quite found that in the desktop version.
