Is the advantage you are claiming useful to the customer ? Does it solve a real problem ?
How is what you are doing any different from the 3000 other guys who are doing the same thing ?
If you are successful, what stops other people from copying your idea and crushing you like the cockroaches that your are ! (thanks Mr Wonderful!)
First-to-market is very rarely an competitive advantage. For it to be an advantage (1) switching costs must be high AND (2) you can capture a large market quickly
Cost leadership is not a sustainable competitive advantage, The low margins make it harder to sustain your business. Larger players with sunk production and distribution costs could lower prices further
