Are you a sponsor of this guy after all? Getting paid to respond to all web comments regarding it? It's quite weird why you have been responding to all these posts with all the passion.

With that said... I work at Microsoft on Windows OS, and the main point that was mentioned is indeed true: this is a claim of this engineer only and his team, and it just seems to be a plan totally misaligned with Windows OS vision of how things should be in 10 years.
