These are just my opinions... Don't target any one specific platform, write your app to be as portable as possible and target multiple devices (android, iPhone, webos, etc.. ) Larger markets have more customers, smaller markets have less customers but much less competition. Price it at $4.99 and then have sales to experiment with different, lower price points. Find the best price and then have a perma-sale at that price. Use the emulator to get started, and once you get your feet wet, develop on the device. The emulator is not enough for serious work.
