Before you ever set pen to paper, or stylus to tablet, you must make a decision about how you will be deploying your FileMaker application. That is, will it be only desktop?
Will it be only iPad?
Will it be a little bit of iPhone, iPad, and desktop?
All of these decisions must be completely decided before you begin any design.

So when designing your custom business application to sell to the world, these factors must be decided first.
Then you can start spending time, money, and effort on the actual development of your great FileMaker Product.
