I think you can use 'briefcases' in vista so it syncs your work and updates it all - although not quite sure how it works, I think you jus put a briefcase on your usb and put all your files in it, then when you work on something at home, and take it to work, the file in the briefcase should update with your work one- you probable need someone more technically minded than me, but I know several people who use briefcases to sync work.
