I've been following the Office 2007 UI for quite some time, ever since I got my hands on early dog food alphas from the Office team. While some might not call it innovation, it just makes sense to me and I think it's a well designed and thought out piece of work. Yes, there are those that are not going to get it and require gobs of training and scream and kick and moan and want their beloved File menu and toolbar back. There is the other group where we embrace it and actually like it. I'll be the first to *** and complain when I'm building presentations where the freakin' buttons are as I'm still getting used to it, but in the end that's it. I'll get used to it, just give it time. I like the look and think it's a good way to go and frankly, Microsoft made that decision long ago and like or not, we have to adapt and live with it (or not, but that's a different blog post).
