Windows Phone 7 is a success for Microsoft, in that it shows the company coming out swinging in the smartphone wars.

Meanwhile, there was no big reveal of apps - in London at least - showing how developers are making innovative use of the WP7 platform. We expect more to break cover in the coming weeks, however.
