I've been using Word since waaaaaaaaaaay back and I actually really like the Ribbon interface. Someone at Microsoft finally realized that giving the same level of precedence to all functionality, despite 90% of it never being used by 90% of users, was really stupid. So, they figured out what functions were used most commonly and put them in the Ribbon. And since you can customize the Ribbon, if you don't like how it works by default, you can change it to suit your needs.
Frankly, I find the Ribbon a far better approach than the glut of tiny icons that word processors picked up in the '90s.
OpenOffice/LibreOffice is still good, but I'd like a Ribbon-ish interface on those, too, at least as an option.
