Very interesting and thanks for the post. Does Windows 10 actually conduct ongoing A/B tests and use telemetry to evaluate them? (for example the interface used by two people on two different computers might look different, or something) I'm intrigued but still very skeptical about the effectiveness of the data-based approach to UI design. That seems to be an area where local, hillclimbing optimization can lead to a mess of conflicting decisions across the OS.
