I went to a restaurant in the middle of nowhere that had a QR code menu as default. None of the major cellphone carriers have service there and the only way to get cell coverage in the town is through a local cell carrier. I was so confused as to why they decided that was the solution for their restaurant.
You could replace Windows with Ubuntu/Mint/Debian/openSUSE/Fedora for even better effect.
