There are rumors going around the internet that are absolutely false. Vista and Win7 do have DRM, but it's only on specific DRM'd files and discs.
For sure the DRM stuff is nothing for Microsoft to brag about, nor is their OS activation process. Their biggest problem will be the fact that people are now looking for alternatives to Microsoft and unless Windows7 really wows folks, their problems are just beginning. I know a number of individuals and non-profits seriously looking at Linux and even MacOS as alternatives. Each OS has its issues, but perceptions are not in Microsoft’s favor.
Not Internet rumors. My long-time developer friends who are checking out version 7.
