PC World has a list of 18 features Microsoft should add to Windows. Here's one of them:
Expose; click to view full-size image.
Available on: Mac
It's an elegantly simple idea, and it has been available on the Mac since 2003. When you want a clear view of all the application windows that are open at any one time, you just press F3, and a ittle feature called Expose arranges them all as thumbnails spread neatly across your screen. Click one, and it pops to the front while the rest snap back into position behind it.
With the release of Windows Vista, Microsoft deployed a feature called Flip3D that attempts to simplify window management in a slightly different way. Flip3D lets users flip through three-dimensional renderings of whatever windows are open on the desktop, but it doesn't offer nearly the same instantaneous visibility that Expose does.
Fortunately, a few downloads can add Expose-like thumbnails to your Windows machine. One little tool called iEx for Windows does the trick for free; but the installation is a little awkward, as you have to drag the downloaded files into the correct folders on your PC. A more refined program, TopDesk, installs automatically in XP and Vista--but it will set you back $20 after the 14-day free trial.
