>>Now - if you REALLY want to see some numbers, look at the Apple app store $$$ compared to the Android store.

Yep, Apple has more than double Android's app store revenue. However, Android has 2 advantages going forward: first, sheer quantity of devices. Play Store is expected to double revenue this year to 6.8B and that's typically conservative when it comes to Android predictions. As of June it had already increased 67%. Apple's store grew 15%. These sorts of numbers are familiar and so will be the result. Second, the Android platform makes it easy for carriers to deploy and charge for apps. Research says that carrier micropayments have a much higher completion rate than app store purchases. If you're not being offered paid apps by your carrier, soon you will be. Again, carriers made Android in the early days and can be expected to do it again for Play Store so they can get their share of $6.8B revenue. So IMHO we can expect another sales juggernaut in the Android camp, this time for Play Store.
