This is where the innovation is. It’s easy to see why the Valley is the centre of everything. At least it’s the centre of iPhone development.”

The really reasons included that other platforms have inferior app stores and other manufacturer’s have a very fragmented device portfolio, and one answer was a bit ironic. They said the path to cash is also unclear, unlike with the iPhone (despite many iPhone developers having a hard time making enough money). Luckily, AdMob was there to answer that question for the iPhone. It said depending on the application, a developer could reasonably expect “15 cents per customer” through advertising. Is that good? If an app costs an average of $30,000 to develop, a developer would have to achieve 200,000 downloads in order to break-even.

MacLeod’s conclusion is that iPhone-vision won’t last forever. “If Ovi, Blackberry and Windows Mobile deliver on their promise, I’m sure the majority will give them the time of day. But right now it’s iPhone, iPhone, iPhone and I don’t blame them.”
