I work / use a total of 5 different computers however, by using DropBox, I have one desktop on multiple computers. This saves me a ton of time trying to make sure I keep my files stored in the same place. By moving your desktop under your DropBox folder, you can easily keep them synced.
You can also create toolbars using the same approach. Especially if you have toolbars linked to folders that are under your DropBox account.
