It looks more like IE7 or Chrome than it does any version of Office.

They:
- hid the menubar.
- condensed common menu items into Page and Tools drop-downs, to apply to the current page and whole app, respectively.
- merged the search and address bars (which imo should never have been separate--I always hide the search bar).
- merged some other buttons (stop/reload etc.).
- plan to simplify the 4 different ways to access bookmarks.

Other than a brief mention of possibly adding ribbon styling, none of the above looks much like Office ribbons to me.

GRemote on Windows Mobile (*shocker*) did it first. Air mouse over bluetooth or wifi, anyone? Click and drag works, on screen scrollwheel works, everything is rebindable. Also works as touchpad, joystick, and game wheel for racing games.

It can be used exactly like the wiimote is used for menus except there is more than one interface you can use depending on what you're trying to control. For example, one that prominently displays media play/pause buttons.

On my HTC Fuze, it feels like a very solid, very capable remote and air mouse. Works with all games, apps, and of course also the Windows desktop.
