<sarcasm>Yes, I'm sure that's what he meant. You have to spend 336 hours straight studying the Office ribbon before you can use it correctly.</sarcasm>
His point (which I agree with), is that all things being equal, the ribbon is a better interface than the file menu. Of course all things are not equal. You've been practicing on that clunky "Word for Windows" file menu for 15 years. It may take you a little time to retrain yourself. People like myself, on the other hand, don't use Office regularly, and find the new interface much easier to use.
Microsoft is taking a calculated risk to separate themselves from their competitors. I think it was a good decision.
