I have been using FolderShare for a while, and I love it. I love it enough to shell out $99 a year for the premium service. Turns out that Microsoft purchased FolderShare today.
This is great news in many respects – and as a Microsoft employee I hope I get to use the service for free now! 
I hope also that partners such as Iomega can continue to support the FolderShare service natively in their hardware – being able to have “hot” backups of all of your files on a drive you can simply unplug and take with you if you need to is awesome.
If you haven’t looked at FolderShare yet, you should. It functions excellently as a way of backing up your data between many machines, as well as a really convenient way of just having your “stuff” ready to be used on whichever machine you happen to be working on.
