Microsoft still thinks it holds the PC market in its hands
Microsoft can keep pushing all it wants, at some point it is just going to push people away from Windows.
The upcoming generation barely knows Windows. Teens today are on Android or iOS, or wasting time on tablets that don't have Windows either. They are used to Gmail and Google Docs. In the next decade, they're not only going to enter the workplace, some of them will end up IT managers.
I'm betting that, come that day, they'll look at Microsoft licence costs, upgrade treadmill costs, service disruption and risk of data loss and they'll say "What the hell?" and move everything to Linux.
So keep pushing, Satya. Microsoft has always been the best reason to go to Linux, one day people will listen.
