Obviously Oracle, the most powerful company next to Microsoft, is hell bent on making money from Java. They are suing Google in an effort to get money from every copy of Android out in the wild and every copy of Android used by developers. I think there is a lot of risk when the cellphone makers do not own the operating system - because cellphone makers want to make money, the os maker wants to make money, and Google wants to make money. Somebody's going to get the short end of the stick and say I'm not playing, and Android will die. With the iOS, Apple owns and controls everything. There is no risk in building a business developing for the iOS.
