Windows: Dexpot is an awesome tool that brings virtual desktops -- similar to Mac OS X's Spaces -- to Windows. It has just updated with a host of new features including full screen previews, lots of smoothness and multi-monitor support.
Dexpot has always been a feature-filled tool, but the 1.6 update makes it a lot nicer. Not only can you view a full screen preview of all your virtual desktops, but it has also improved the Exposé-like catalogue feature, added support for multiple monitors, given the ability to assign applications to specific desktops, lets you add different shortcuts to each desktop, and a lot more. If you don't have Dexpot yet, the new update makes it a must-have tool for Windows, adding a stack of features to your desktop that you never knew you wanted.
