Where is this all going?
There's a lot of technology and a lot of choice when it comes to wireless devices. Whether you choose Flash, .NET or Java does not really matter. All that matters is that you get involved with the game. In addition, you must be prepared for change. One thing companies such as Nokia have taught us is that they adapt and modify rapidly. Think about this: almost all phones today have cameras on them, but just a year ago that was a luxury item.
Think fast, think small, think mobile.
