Improvement on functionality is one thing, changing the UI like changing your underwear is quite another.

 

How does the new Office 12 "know" what I need at any particular time? End-users are already tired of having new windows/new bits of info appear or change in front of their eyes based on what I like to call “Microsoft Intuitionism.”

There was a time when I enjoyed new versions of Microsoft products. It was play-time. Now I have grown tired of major changes in UIs. Even if this is all going to be better, I can't help but complain...
