Agreed with TVeblen; I don't hate the Ribbon, but the legacy text menus were IMHO much faster to navigate.
Especially when you're trying to guide someone else via text communications like email. Sure, the Ribbon makes for eye-catching screenshots, but honestly it's simpler and faster to just type out "hit
Edit -> Pa
ste Special ->
Insert from file",
then include a screenshot of the file select popup dialog or whatever; the recipient of my email will know exactly what menu options I'm talking about right from the text.
With the Ribbon UI I almost always need to include a screenshot for what exactly on the Ribbon they're supposed to click, with additional arrows drawn in Paint or whatever.
I use
Classic Shell for my Windows 7 Start Menu; similarly I kinda wish there was a Classic Shell for MS Office

Heck, TVeblen's suggestion for something like a "Legacy skin" would be great.
