Internet pervasiveness in Peru
The omnipresence of internet cafés and network game shops is incredible in Peru. Even on the Altiplano, around 3800m, far from tourist footprints, you can get fast internet connections. The vocabulary of these is also fantastic: "speedy internet", "speedy veloz", etc.
Coupled with cafés, laudromats, drugstore, baby clothes and other curious things, it's stuning to see connected areas where people don't even have access to water and sewage.
Thinking about other communication services like the llamadas, it's interesting to note how technologically-mediated interactions are important in that part of South America. I found it more apparent in Peru than in Brasil for example.
