Re: Square Wallet, the Apple Store, and Uber: Software Above the Level of a Single Device - http://radar.oreilly.com/2012...
"A point that gets lost in all the tech hype is that these use cases work because both the owner of the business and the service employee give a damn (If the barista is too busy playing angry birds to look at their Square register app, that place won't get my money !!) I remember returning to my local (the Paekakariki Hotel) after 18 months absence overseas, sometime back in the 80's. My beer was on the counter, open, before I got to the bar. Debbo didn't need a computer for that." - martin english
