It will be worth your time. Its kind of like Stephen Key's approach, but more for technology/products. Often times first thing I want to do is jump into code, and it's the last thing you should be doing. Proving the market is critical, and the only way you can prove it exists (for most companies) is to fake sell. When people tell you, I would buy it if it had this feature, they are often lying. Unless they are willing to pony up their credit card, you haven't solved the problem imho.
