It’s Not All About the iPhone
The New York Times shares venture capitalists’ advice to develop applications for all mobile platforms:
Startups should “intelligently hedge their bets across multiple platforms,” advised Richard Wong of Accel Partners. His firm has invested in mobile games and application site GetJar, “the store for the other 3 billion phones that aren’t iPhones,” as Mr. Wong put it.
Assuming you have the development resources to go after every platform, sure. But the facts remain that the app store is immensely successful, the iPhone is an exciting new platform for developers, and the SDK is freely available.
If you have to choose a single platform (which many developers do), the choice is pretty clear.
