You have a funny definition of truth.

The rumors of the death of the desktop have been greatly exaggerated. WinXP is (finally) reaching EOL and they can't run forever even if you don't care about security. Win8 is the new Vista and people are happy with Windows 7 for now.
The PC market can't grow forever, how close it is to saturation I don't know but there is still a lot of money to be made in mature markets like autos, etc. MS needs to get its act together and defend its market share or it might end up like GM.
I'm not speaking for MS, but I think they want to be seen as a growth company, not a stable, mature company. They want to maintain their market share, but the "opportunities" for new growth probably lay elsewhere, so you'll see investment away from PCs into areas where new money can be made (while still trying to preserve old money, of course). Even the car needs a new remake to create new market share and hence opportunity; e.g. Tesla and electric cars.
By the way, OSX is hitting 15% market share in the US.
