The Techie Husband just showed me a new beta product from Microsoft:
SyncToy v1 Beta for Windows XP.
It's a tool for syncing data between different machines. It's got a nice XP GUI. You set up one or more pairs of folders, and have different options for syncing these folders. I'm not quite sure if you can sync things like RSS feed profiles on work and home computer throught the internet or something, I'll have to test it a bit more. But for me, just setting up a syncronisation / backup of my development project files in a few easy steps is very usefull.
