WinPLOSION and TopDesk: Exposé for Windows

One of the neatest "wow factor" features of Mac OS X is Exposé, which, with a keystroke, will show you a "map" of shrunken versions of all the windows you currently have open for easy task-switching. For Windows there are at least two utilities that emulate Exposé's functionality: WinPLOSION and TopDesk. (If you want to know what the effect looks like, check out the Flash demo on the WinPLOSION site by clicking on one of the screenshot thumbnails.) Though they use different keyboard shortcuts, the programs seem fairly comparable, both featuring the same three main functions of Exposé: Show all windows, show all windows that belong to the current application, and show the desktop. Unfortunately, neither program is free -- they both cost about $10 -- but WinPLOSION has a 7-day free trial and TopDesk has a feature-crippled unlimited trial.
