Sorry, I left out a *not.
I vehemently disagree, in 2007 NOBODY liked the ribbon. My wife's company refused to upgrade until absolutely forced to because it was such an atrocity. The most glowing reviews I ever saw were "I guess I'll get used to it eventually" and/or someone who used office once a year and found navigation easier when the extent of their workflow was changing font sizes.

It is a little hard to parse what you mean, but Microsoft did a quite substantial amount of research leading up to the ribbon. A quick search on the net will lead you to summaries of it.
