I think the Beagle Board stuff goes back to the summit last year: Nokia knew it'd be ages before Rover saw the light of day, so encouraged platform hackers to try the Beagle - and knew they were using it internally initially as well.

There was a very key comment from Ari Jaaksi at OSiM World saying that Nokia had no interest in licencing Maemo to other hardware manufacturers. But then he also argued - many moons ago - that two devices were better than one ;-)

I'll be very surprised if any other hardware manufacturer announces a separate Maemo device; but then I'm mostly surprised at the smaller, thicker, it's-a-phone Rover. So take my surprise ratings with a pinch of salt!
