But it's not a gamble because it's the same every time. It's high quality every time. It has the weight of a quality brand behind it. Maybe it's a small gamble the first time you buy it, but after that it's not a gamble. The argument isn't about the price of your app or their first cup of Starbucks coffee, it's about the price of your app or another Starbucks coffee.

People know Starbucks; people know Starbucks coffee. It's a very stable and well known experience to regular customers.

People don't know you; people don't know your software. I don't know if buying your software will actually cause me more inconvenience than convenience. (Buggy, bad UX, hard to uninstall, installs additional crap like browser plugins)

That's why buying an app is a gamble, and buying coffee isn't. That's why you cant make a good argument by comparing the price of your app to the price of a coffee.

EDIT: Actually I guess the $4 drinks are a gamble afterall. My only Starbucks experience is "normal" coffee. Which I guess is more in the $2 - $3 range.
