I have no explanation for why Microsoft has started aggressively innovating again (with the introduction of Satya) than my theory that US DoD realized the country's tool of dominance in the future will be predominantly with tech superiority instead of military power. Microsoft's new strategy of running everything on the cloud aligns with this, even if it may have been also motivated by the fact that most people now only own a battery-constrained mobile device and laptops getting smaller and thinner.
