I think the more important statistic is the profit Microsoft makes per Android device, compared with the profit per WindowPhone device. There are far more Android devices, so it's not surprising they make more from that "licensing" agreement (I'm loath to call it that when it's more like extortion). I find it hard to believe that MS would prefer (and make more money from) an Android dominated market compared to a WP7 dominated one, so I'm pretty skeptical of the idea that MS are holding back on WP7 because they don't mind Android dominating. I could be wrong though, maybe their Android licences really are that lucrative, and in that case God help us all because the software(-patent) industry is even more fucked than most of us ever imagined.
