Microsoft likes getting spanked by Apple. If not, they better learn to like it, because they keep positioning themselves to be a better target.
I'm a happy subscription music user. It's a great option if you like to explore lots of new music (if you don't, it's not). However, Microsoft hasn't been successful promoting it, and this is another bad move. Although I've spent hundreds of dollars happily renting music for years, I've never purchased DRMed music and never will.
Forking PlaysforSure into incompatible Zune was a bad and disturbing move, but it didn't affect me directly. Changing it to "Certified for Windows Vista" is so idiotic--it's hard to imagine much non-Zune Windows media stuff surviving. Unfortunately Zune is foolishly based upon the one bad thing about the iPod (a closed ecosystem). I guess I should start looking for alternatives.
Microsoft's Reality-Distortion Field apparently allows them to convince themselves that Vista will soon be ubiquitous. And, they should prepare for and encourage this by giving Vista more visibility; Vista-branding all the Zunes and music they expect to sell, even forcing music partners to use Vista branding ('till they're extinguished by Zune). It's crazy; and Microsoft doesn't appear to be coming up for air anytime soon.
