Congrats!
Well the iOS has far more devs giving rise to competition. This ensure the prices are kept low and the apps perform well. I do not one bit consider the number of apps as a benchmark for any platform.#aproxymate, if you are an app junkie, you might find WP7 limited in that area. Otherwise, purely in terms of the touch experience (apps or no apps), I would rate it at least on par with the iOS.
