KDE is one of the desktop managers (for the sake of an easy life think theme) that has been available to Linux for many years. And now it looks like it might be made available for Windows.

Although it's the Linux desktop manager that looks the most like Windows, I think some choice would be a good thing overall. Some aspects of KDE, such as the new tabbed Start menu, look rather good. In addition it comes with it's own office suite. It's not quite as capable as the heavyweights of Microsoft Office or OpenOffice but it's much better than surviving with WordPad.
