Haa..you joke, but I bought a Nokia 521 running Windows 8.0 for $50, unlocked. It still does a ton more than a dumb-phone, though. Just enough internet to be useful, scan emails, check out twitter, but not as slick to make you want to waste a lot of time using it.
But will it blend?
I don't think that's the narrative Microsoft was going for.
This is a pretty good idea, actually. I might have to try it someday! :-)
