The thing that bothers me more than ribbon itself is how much the performance started degrading once they introduced it.

I got MS Office 97 working in Wine recently, and it's still shockingly capable. There are lots of formatting options, it can read my system TTF fonts, and it's since it's nearly thirty-year-old software, it runs ridiculously fast on modern computers.

I don't feel like MS has added many more features to Office that I actually care about, but I feel like the software has gotten progressively slower.
