There are presumably more Android phones and devices out there now than there are iPhones (and iPod Touches). However, it seems Android users keep holding their wallets much closer to their chests than iPhone users and iOS users in general.

Case in point, according to a new report from Distimo, the App Store for iPhone generates almost 4x as much revenue as Google’s Android Market in the US. This also includes revenues from in-app purchases. Even looking at just the App Store for iPad, it outclasses Android Market with 2x the revenue.
