Seriously, you only found one shortcut for the Windows key? I find that surprising. There are quite a few more: Win+Arrow Keys can be used for window management (only in 7, to my knowledge), Win+R opens a run dialog, Win+D takes you to the desktop, Win+F opens a search window for the system, Win+E opens an Explorer window, Win+Break opens System Properties, Win+Spacebar peaks at the desktop (only in 7, to my knowledge), and Win+L locks the currently logged in account (useful if you live in a dorm or other environment where people like to mess with your system when you step away for a moment). There are many others, but these are the ones I find most useful. YMMV. I'm not sure what other simple key combinations could be used for the same functionality. And if you're using Mac OS or Linux with that Windows keyboard, it works as the command key or super key. So yeah, I'd say it can be quite useful.
