Yeah, well, Outlook is a different story. The Ribbon interface isn't really suited to a mail client, and Outlook has so much historical baggage that makes it ridiculously hard to use. I try my best to not use it, so I don't know how much it's changed.
But Word, PowerPoint, and to some extent, Excel? The Ribbon is really well thought-out and easy to use. It feels intuitive in a way that the old bloated menus never did. And the command search feature is actually really useful, and teaches you where a command is located so you can just go straight there next time.
