Uncertain results? There was a report not too long ago that showed that even though the market share was smaller on the WP7, a lot of apps were outselling their android counterpart. Sounds like a little bit of both sides being stubborn.
I'll preface with, as usual, I'm talking out of my ass, but: There was a similar effect with Mac software, I recall. Even though there was a smaller install base, the few games which came out for Mac sold relatively well. The reason seemed to be that because there are just so few games on Mac, the audience was ready to pay for whatever they could get.
