Ribbon Shots
OK, for those interested, here are shots of the ribbon as they shipped in the beta that was released yesterday. These are more or less finalized – there may be a few tweaks between now and when we are done, but not many.

There are both XP and Vista versions (thanks Dan!), and I have grouped them by area. The XP versions are at a resolution of 1024x768, while the Vista versions are at 1600x1200 – this should give you a good example of how the ribbon resizes for different resolutions.
