Obviously this is all speculation, and no solid proof yet that Microsoft invests less on Windows. But what do you think if it were to come true that Microsoft now focus only on cloud services? It's kind of like the same move IBM made when they decided to move away from hardware to consulting.
It's possible that they want to move away from PC desktop OS market, although financially that wouldn't be a smart move. Windows is still being used by majority of people.
Funny quote from the video:
Users spending nearly 5 hours per day on the console!...Do people work on this country?
Thoughts?
