Got two (or more) computers and want to get to the files on each?  Check out FolderShare.  From JK on the Run:

I have been using my HP tc1100 Tablet PC alongside a Sony U71 for a few days and the solution I have chosen to keep them in sync is FolderShare, a free (in beta) service from the Windows Live offering from Microsoft. FolderShare claims to be a simple solution to keep multiple computers in sync no matter where they are, provided they are connected to the web. I have been using it and so far I am very happy with the service and how well it works.

I’ve tried FolderShare a while back and was impressed.  When I go back to multiple computers again, I’ll be sure to give it another whirl.
