Wow. The UI, while attractive, will take some getting used to.
The ‘ribbon’ concept is really interesting. I’ll admit being a little overwhelmed at first, but the development team seems to have put a lot of thought into not only where commands are located but also how prominently they’re featured on the ribbon. I think I’m going to like it.
So far, I’ve only played with Outlook and Powerpoint. I’m saving Word and Excel for when I actually need to open a document in that format.
