Haven't you noticed you were wrong about "no DRM on Windows". That's the start.

They have DRM for apps, DRM for music, DRM for widgets, DRM for apps that you buy via their Zune and Windows Media marketplace, DRM for podcasts, DRM for drivers on Windows.

Which part of that are you overlooking? You picked a wrong example, I linked you to parts that correct your mistake; if you wish to remain oblivious that I'm talking about DRM as an entirety - there's a DRM layer in Windows - then have at it.

I'm quite sure you'd see I was also talking about apps and much more.
