Microsoft have come out as unlikely allies in the fight against DRM. It seems they're helping to educate consumers on why DRM sucks. Their new player won't work with product bought under their "Plays For Sure" DRM-promoting scheme.
If the record companies were smart, and we all know they're pigshit thick, they'd insist Microsoft provide consumers with an upgrade path, at least just this once. Then their DRM might be more palatable. Of course, they're still basking in the afterglow of all the cash they made when everyone replaced their collections in the vinyl-to-CD upgrade cycle. They think with this DRM stuff they can do that every couple of years.
