Fantastic answer! One thing to add, is that if you have a big market, and they get 90% of it, 5% of it to you, might be enough to be successful. You are worrying too much about their product instead of improving your own. As Patrick also said, go out and talk to customers. Often you don't need a finished product. What we did, was actually quite different, we talked to a bunch of customers _before_ we began developing the product. We did that for two reasons. 1) Get to know your customers, and learn about their pain points. Try not to fix all their issues, but if you can find a few common issues and fix 80% of their problems, you are in for success. 2) By talking to them you got your first beta testers. Let them in before your are finished (You shouldn't have any errors, but you might lack some features (we didn't have a change password for starters)). This relationship will make it easier to sell to the customers, because you have listened to their issues, and actually fixed their problems.
