I disagree. Sure you will lose some people going to market early but the idea is that you gain people who are major product advocates, people whose problems you are solving so well and your product resonates with so strongly that they will be patient while you work on the other stuff. And you better understand THOSE people, and as you improve your product for both the major advocates and add the extra nice to have features. Then you've figured something out and you may actually get back some of the people you lost at the beginning. Because the people who loved you all along will tell them "not having feature Y is not a reason to ignore the product because I've been using the product since day 1, it's gotten a lot better and now it has feature Y."
And that's when you've done a great job. Write a piece of software that solves your core problem and go to market early.
