No, I don't work for Microsoft. And I didn't ever think I'd say this about Office, but this upgrade comes with a vastly improved user experience. The grouping of functions on the toolbar is very good, and toolbars that contextually adjusts to the situation hand-holds me trough things that were always (in my opinion) hard to find and do. This, together with much better default templates and styles than before, actually made Office a little more fun to use.

And one minor improvement is actually quite important: The 65,000 rows limit of Excel spreadsheets is now gone.
