First, I know companies (small and medium) that can't stand Quickbooks. If you want anonymous testimonials, I'll be happy to post them.

Second, the apps that I develop (and apps built by most developers that I know) are not ones that fall into the commodity area, at least not the way Quickbooks is. Plain and simple. Again, I think you're blowing the Quicken model way out of proportion. Theoretically, Quickbooks is more a service than a potential ROI investment. I truly do not understand what it is you're trying to prove with this.
