Where are all the Android apps?

Venture Beat had an interesting article asking where all Android apps are? I think its not such a mystery and its not a huge indictment of Android. There are five major smartphone operating systems with a future: iPhone, RIM, Windows Mobile, Android and Symbian (notice I didn’t mention Palm or LiMo).

For anyone who does serious mobile app development, you cannot afford to target all of them (when it was two or three you perhaps might have tried). Android easily falls off the priority list for every mobile app developer I’ve talked to. With a platform like Rhomobile (are there others?) you can write it and target primarily iPhone and Blackberries for volume, but still get Android, Windows Mobile and Symbian.
