Very interesting analysis. I'm in the process myself of spinning up a saas with multiple forms of payment. However, my UX basis for bitcoin would be something like gyft which uses bitpay. These transactions are instantaneous and directly from the users wallet (any wallet). That seems to me to be the standard of service at this point. I'm missing the advantage then of using coinbase. I only see it limiting potential audience which seems rather counter to the idea of accepting bitcoin in the first place.
