If you bought Xbox video, and you use Windows Phone 7 or Zune, you're going to be able to continue using it until Feb of 2014. After that, nada.
Microsoft gave some crap about how they improved on the video and offerings. Translation: if you wanna keep using Xbox content, get a new Windows Phone device, preferrably the Lumia which Microsoft effectively own.
Zune? I get that. But Windows Phone 7. Not so much. It's still pretty new. It's the OS that has been delayed over and over until Microsoft managed to ship it against some already entrenched smartphone heavyweights. It, along with Blackberry, had owned the mobile market. One theory I've got on why Microsoft is chucking WP7 now. There were not many takers to begin with.
Kinda like Zune I guess.
Well, I'm sure there is a lesson in here somewhere. In this day and age, if you want to make sure your digital content are available for the long-run if not forever, make sure you go with a platform that has legs. Like iTunes or Amazon.
I want to add Google but its history of killing off apps and services without warning has me worried about buying media or music from them.
