Like most people, I work on a collection of work-in-progress documents. Over time I started loosing track of where the latest version of a particular document was left... my desktop, tabletpc, laptop, or on my home machine.
Then I remembered a relatively unused feature of Exchange+Outlook which is “Free Docs”. If you didn't know already, you can directly drag a document into a folder in your mailbox. Here you can leave the document while you edit and develop it over time. Coupling this with Outlook Local Cache Mode, you can keep multiple clients in sync with the latest version of a document regardless of where you are or which client you decide to use.
