Get back your machine (from Windoze)...
If you are stuck with Windows on your company machine (or laptop), and want to recapture your machine from the clutches of Microsoft, Cygwin is the deal. Cygwin is a small unix core that works as an app with windows, and gives access to most Unix programs that you would need - a good shell (with tab completion), midnight commander, and even a minimal desktop manager like Window Maker.
