Do you covet the Mac OS X Dock, the bar of icons that runs along the bottom or side of the desktop and offers access to frequently used programs? If not, you should, because it's one of Mac OS X's niftiest features. So nifty, in fact, that the Windows 7 taskbar will have its own Dock-like feature.

No need to wait, though: RocketDock offers similar features. You can place it at the top, bottom, or either side of your screen, and it contains icons that you can click on in order to launch programs. You'll find My Computer, Recycle Bin, Control Panel, and several others, for starters. You won't want to leave it at that, though--and you don't have to, because you can add new programs to the dock simply by dragging and dropping them. If you don't like the way the icons and the dock look, you can change that, too, by altering the opacity of the icons or applying different visual styles to the dock. It's free, so if you want a new-look desktop, it's a great download.
