I've worn both product and developer hats, and honestly the way I see it is: You need to decide whether you are building tools or toys. Neither is bad, but you should decide on one and stick to it for the product. You can make money building tools and you can make money building toys. But you're going to turn away customers if you first make a tool, then turn it into a toy in the name of "simplify" and "making it sleek".

As a professional user, I bought a $2,000+ workstation. I expect the applications I run on it to be powerful tools, not toys. But, there are also plenty of other people who run apps on $200 mobile devices who are fine with fewer features. Pick one market and go after it.
