Best Cities to Live in Colombia

I visited Poblado for about a week. I had absolutely no problems with the Internet while I was there. Maybe it was because I was in Poblado, but I never experienced slowness or anything of the sort. Pros of Medellin: spring-like weather, inexpensive, reliable Internet, plenty of shopping and creature comforts, cosmopolitan, friendly people. For cons, a big one is air pollution. Medellin is located in a higher altitude valley. There are many old cars, buses, and (especially) motorcycles belching exhaust into the air. It's difficult for pollutants to disperse because of the city's geography. I.e., there's plenty of smog and there's no debate regarding the negative health impact. To Medellin's credit, the city acknowledges the problem, monitors pollution, issues advisories, and is trying to change, but obviously change doesnt happen overnight. Other cons: The more Spanish you know, the better (not really a con, just is), gringo price gouging, some safety issues (use extra common sense).
