Presently, anyone using an Android-based phone can download applications from the Android Market, which first started offering free applications in October '08. A drawback to Android application developers, however, is the fact that the potential Android Market user base is fairly small right now, as there is presently only one Android phone available, the T-Mobile G1. However, in the coming months we're also going to see more app stores come online for additional smartphone platforms. Nokia will officially launch an app store for its Symbian OS-based smartphones at Mobile World Congress on Monday. Microsoft is also getting in the game for smartphones that run the Windows Mobile OS, with Steve Ballmer delivering the keynote speech at Mobile World Congress as well."
