While it’s still way behind Apple’s App Store and Google’s Android Market in terms of app quantity, the folks at RIM should still be quite happy to announce that it now has over 10,000 applications in their BlackBerry App World application store. While Apple and Google both tout over 100,000 applications in their stores, 10,000 apps is still not a figure to be laughed at. Next RIM will have to ensure that the quality of the applications available on the App World are up to scratch, and hopefully it’ll pose a strong challenge to its rivals.
