Is Square attempting to market consumer uses for their product? It seems like a device and service to process credit-card payments isn't really right for the masses of consumers that flood through Apple stores.
Count me in as one of the people using Square as a consumer device.
Ever been out to dinner with friends and when you go to split up the check, everyone wants to trump because they don't have cash and only have a credit card? Boom. Now I'll just trump and then have everyone pay me back with Square. The convenience is worth the inexpensive transaction fee.
The liquor store down the street just got a 27" imac for their POS, and the hydro store two blocks down has the same POS. Small business owners are notoriously incapable of understanding tech.
