Far be it from me to criticize AT&T, one of the world's largest cell-service carriers, but come on. Reception sucks. Dropped calls aside, you have to give to AT&T for this crazy-prescient commercial from 1993 in which they predict the existence of electronic ticket kiosks, video conferencing, e-books, tablets, and even buying stuff online.
It looks like the only technology they didn't anticipate is flatscreen TVs. BOOM! Take your convex screens and shove that in your mind garbage, AT&T! But really, AT&T, how did you know?
