100% can confirm. It always takes me ages to find what i need in the ribbon interface. Especially the things that aren't visible all the time. First time I was asked to print something, I really struggled with that. And it used to be File->Print. And I have no interest in finding out if they made it easier or worse to do things like conditional formatting or alternating row colors in tables.

Regarding the issues with formatting: It's Microsoft's fault. They're doing this deliberately to get rid of competition. And they'll ensure it stays that way in the future.

There is one exception, however: You need to install the correct fonts. If you don't have the specified font available, a document will look differently and things might get misplaced, because your characters might now be wider or narrower.
