Well, Steve Ballmer wasn't exactly an innovator - just kept milking the cash cow. Satya Nadella seems way more tuned into the zeitgeist. His heavy bet on OpenAI may seem excessive, but at worst it's going to be cheap insurance and at best may be a game changer. I think Google's producing Android was a reaction to BOTH iPhone and Windows Phone - they didn't want to be frozen out of the mobile advertizing market by competitors that owned the platforms.
