My feeling is that Microsoft is slipping in a lot of areas right now and alternatives are being examined where there is possibility to do so.

Vista is/was probably a big mistake, and key features are being turned off in a lot of larger environments for the sake of compatibility with older applications.

The world is changing and there are alternatives to resource-hogging and expensive software. You wanna stay in the game? Then get with it.
