> It's all in the number of devices out there. As the number of devices goes up so should the sales. Actually I disagree. The Android marketplace isn't compulsory so many people would be getting their apps from other sources. It's kind of like comparing the the approval rating of the leaders of North Korea with that of the US. Before the iPhone came along nobody would have thought of using a centralised 'app store' as the measure of a platform's strength.
