Hi! I also registered, but you missed one device in the list: Samsung ATIV S. I don't own one, but just wanted to tell you. Oh and since you used a Lumia 900 for the picture above: Will it come to WP 7 as well?
I absolutely agree with you! It's a great game - simple but really addictive. Hopefully we will see some more metro inspired games in the future :) I'm looking forward to the update with TrafficTiles and achievements :D
