If you liken app stores to race horses, Apple is the biggest, baddest thoroughbred in town. Google Play is a fine specimen with some distinct qualities but has a lot of work to do in the practice yard before catching up. Everything else is an also-ran. Windows Phone has been growing rapidly, increasing from 40,000 apps in Nov. 2011 to 70,000 at the most recent count. Then there is BlackBerry App World. For all of Research In Motion's troubles, its app repository is tied with Windows Phone at 70,000, which includes 15,000 specifically designed for the BlackBerry PlayBook. There are no tablet apps in the Windows Phone Marketplace, mostly because there is no Windows tablet (well, one worth anything).

German BlackBerry blog BlogBerry.de sent us over an infographic (through its content promotion specialist BlueGrass Interactive) breaking down the "reality" of the native app stores. It quotes RIM VP of developer relations Alec Saunders as saying 13% of BlackBerry developers have made $100,000 or more off their apps. We have heard this song and dance before. Take a look at the infographic below and let us know in the comments what you think of the BlackBerry App World, its quality of apps and whether or not it is a wise business decision to build any apps for the BlackBerry platform these days.
