1) AP - Discussion on the victory (Office Ribbon) that led to Julie Larson-Green being made head of UI Experience
2) WSJ - Fact-less story about how Windows 7 is fixing the failings of Vista. No discussion about UI-inspiration. The closest was a hint to "quieting the system" that is directly addressing the UAC-faults that everyone griped about with Vista.
3) Fast Company - An overview of features that is devoid of anything but marketing information
The only thing 'useful' in this blog post was a link to the Windows 7 Design Blog. And in there, it describes how they highlighted items to improve, Except there's no reasoning behind why they thought these items were necessary, and the requirements they did identify seem to lead directly to their final solution... an indicator that the requirement was actually thought of after the solution.
Debunking, this is not. It's a collection of irrelevant posts and a link to an encyclopedia. It does not address the point it attempts to make and is frankly, a waste of time to read.
As for my issues with Windows 7, removing the email client, requiring users to sign up with Windows Live just to use their Windows Live Mail address book (when the Windows Address Book is perfectly fine), and making interface changes that require more clicks to accomplish the same tasks are my reasons for not caring for the changes... not some incremental innovations that appear similar to other operating systems if those other operating systems have good interfaces.
