UX-wise, this an extremely basic (to avoid saying lousy) article. I ended up with the impression that their source of data is pretty much the feedback from beta users (which is great but highly skewed - to the technocentric pole - data). I would like very much to know more on how they are working with end-users. Are they using ethnographic methods? Observing how Windows is used in the real world? How are they addressing cultural diversity? Are they having focus groups, interviews? What kind of telemetrics they gather? What have they discovered from their huge user base (and huge funding for their design project)? This would be much more interesting - even to the layman, I think - than empty phrases such as, say, "people aren't squares".
