Just want to point out that the Hantro GStreamer video encoder plugin on the tablet is already closed, and Nokia did deals with Skype and Adobe for the tablets...

It wouldn't be a particularly big deal to put a couple of closed DRM media player plugins into the mix. They might have to make it closed 'all the way to the speakers / screen', but I really don't believe there'd be outrage in the community over it. Those who don't like it wouldn't use it.
