There was a question raised on this. Here was my answer:
iPhone has an early start in Mobile Apps. Till few months back it had more than 50,000 now the recent number is being floated is 100,000 apps. This is a huge market. The iPhone also enabled individual softwre developers to participate in this money making process. Considering Apple’s strategy of innovation (even at the risk of making previous technology absolute,) I would expect the iPhone would also be addressing usages like Game Console, Home Automation Controller, iReader (books) etc. Google Android would continue to do some catch up game and may have some cool edge. For example, Google recently announced turn-by-turn voice assisted GPS. But iPhone has an advantage, that it is not only a platform, it has hardware from Apple which would keep on adding new technologies to add more fancy software’s. having said that many of the iPhone apps developers may also port their softwares on Android if it takes a momentum. I am more interested in watching google strategist position their mobile OS with Chrome and whether Apple matures iPhone OS into a platform for iTablet like devices or comes up with something else. It would also be interesting to see WebOS from Palm, and a direction from Microsoft CE. You can notice that as long as the opposition it fragmented, iPhone has an edge.
