Microsoft still has a chance
Microsoft is a huge successful company, and is not going anywhere. If anything, they will have to scale back in a few sectors.
They need to make Windows Free, maybe even open source (ok, that's a pipe dream)
Absurd. The near monopoly of Windows gives them the muscle to keep better products off the market. They are also the only player in town when it comes to PC OSs (sorry Linux), and the Windows tax is not something that they would or should give away for free.
Then they need to invent all kinds of stellar business apps that integrate with it flawlessly...
and license those apps to businesses. Businesses will pay for supported apps, because they like to be covered if something happens (thats how oracle makes money)
That has never been their business model. Either buy the better app and rebrand it MS, or else crush the competition through their Windows monopoly, e.g. withholding parts of the API.
Basically everything Microsoft is currently doing is wrong. They are digging their own grave and anyone with any tech savvy at all knows it.
I really don't think that you speak for the "tech savvy."
