I clicked your link, and I actually like how that office suite has the options on the left rather than the top. Like it was made for widescreen monitors.

The only other office suite I've seen do that is Apple's. As a Mac user, I recognised the style immediately. So I use iWork stuff because it's on my Mac already and it's good enough for me. I like the way LibreOffice is looking but I don't need another office suite. But I really like the way calligra looks. It might need some polish, but they have some good ideas.
