In the 2000s I encountered a lot of Microsoft employees who totally did not get what it meant to have partners in an industry. They reminded me of some of the worse people I ever dated or lived with.
As an example at a .NET conference I heard Microsoft laughing about how much money HP lost in the mobile space on hardware. I also know that MS charged them a pretty penny for OS licenses and software licenses.
My experience with the HP sync utility MS provided to HP and how it made a $1,200 mobile machine worthless.
