Buenos Aires is great, I lived there for 4 months, Internet is easy. Broadband is not bad in Delhi India, everyone speaks english and you can outsource well, plus you can buy those sweet wireless broadband sticks and have wireless everywhere. Brazil was okay for work, but the Internet isn't as good as Buenos Aires. Italy is terrible for wifi, as is Spain generally. Those are the places I've digitally nomaded, but I'm heading to cape town later this year.
