Here is some more relevant data The folks at http://larvalabs.com/blog/android/android-market-payouts-tot... say that only 13 Android apps have got more than 50,000 downloads. A greater number of iPhone apps have got more than a million downloads.
This should give you a good indication of two things
(a) which platform successful developers focus on and
(b) how many Android users vote with their wallet to indicate that the Android market has good apps.
Edit: It is interesting to see the downvotes canceling out some of the upvotes :) I understand that some people may not like these numbers, but the commenter/reply suggesting that the numbers are "misleading" (because money-making iPhone apps are older) is mistaken.
Consider the fact that the iPhone Angry Birds app has got more than 4 million downloads in less than 4 months. A paid iPhone app in the #1 slot for a month can get more than a million downloads in that month. Now think about how many downloads a #1 or #10 paid Android app can get in one month.
