If the market isn’t sigficanlty large so that 144 people will pay 99 cents a year for the app (the minimum requirement to cover the developer’s cost) than the application is probably not tested and developed to a high enough standard that I want to run it on my cell. I consider my cellphone production hardware, and treat it as such.

It might be, but we'll never know. There might not be enough people willing to test a new 1USD app from a hobbyist.
