Although you can access the same tools on the ribbon, as you say, it needs extra clicks.

Since when has requiring extra clicks/keystrokes/time to do some been an improvement? Some might say that it helps less skilled users. It's easy to train people, it's harder to have to write a custom interface to get back the speed and functionality lost be this kind of change.

To me an upgrade means nothing will take more time/clicks/... , no functionality is dropped, and at least some extra functions are added.

Seems to me the Office 2007 isn't an upgrade.

One question I have is as an Excel developer, I often create custom toolbars and menus for my apps. Given there are no toolbars, how will this work in 2007?
