I don't know what things are like in other countries, but here in Australia dialup is available anywhere in the country from quite a few different providers, including the main ones such as Telstra, Optus, Westnet, iiNet, etc. Unfortunately like most other countries, ADSL isn't really available in a lot of places here in Australia, only in built up areas, and as such if you go into just about any rural part of Australia, you'll find that a lot of people still depend on dialup, while I have 3G and a lot of people now have satellite broadband, a lot of people either can't get 3G coverage and/or can't afford satellite and have no choice but to use dialup.

Yes, dialup is slow, pathetic, last-century, and just so un-kewl, dude. But for a lot of people, including me up until a few months ago, its either that or two cans and a piece of string.
