And devoting resources to Win Phone 7 is going to be a big win? How does one know? What if Kin caught on and Win Phone 7 flopped? Some people would be praising the Kin team and others would be making fun of MS for wasting their time with Win Phone 7.
I think all of these mobile efforts by MS are doomed, but I don't see why Kin was a worse idea than WP7.
