If you use multiple computers like me then one of the things you want to do is synchronize certain files and also IE Favorites. Previously I used to use the Live Mesh Beta software to share a directory under the IE’s Favorites directory that I synch with a similar directory on all of my computers.
Now the updated Live Mesh make it even simpler. You now get a option to turn on/off IE favorites synching.
This article has more details on all the other features in the new Live Mesh.
