Windows 7 - "Show Desktop"

I'm evaluating Windows 7 to see if it can be recommended to our clients as the new desktop platform. So far it works great with a few small exceptions. Most of the negative points that came up have to do with the changed interface and not the speed or reliability of the system. Microsoft have done away with several very useful and familiar tools, buttons and features. One of them is the "Show Desktop" button present in the Windows XP/Vista quick launch toolbar (right next to the start button). It was one of the best additions to the toolbar since Windows 2000. But the icon is not present in the Windows 7. At first I thought it was completely gone, but then a quick search with Google gave me good news - it has changed it's look and was moved, but it is still present. Now it is located at the very right of the toolbar (just right of the clock - yes, see the little vertical rectangle?)
