I'd take it a step further. People don't weigh the coffee-purchasing decision at all. That's the key difference. Coffee buying has become a routine, whereas app buying is consciously considered. The process of considering and purchasing an app is -- at least for most people -- not a daily, habitual, automatic one. And so it is with most purchases in life. Anything we're not doing on a super-regular basis does not become automated and relegated to subconscious action to the extent that a daily routine does.
That's not to say that buying an app can't become a daily routine, of course. Anything is possible. But it seems unlikely for most people.
