The bottom line is actually quite stark and depressing.
Microsoft are building their future upon an architecture that is fundamentally flawed from top to bottom.

Microsoft like to think that the world needs their software, but I see it like this: if I fart in an elevator, someone else is going to have to breath that air.
They might not want to and they certainly won't enjoy it, but they often don't have a choice...
