Density seems to be a challenge, not a solution, for AT&T in those prime markets. I can't imagine providing 3G coverage in Taipei or Kaohsiung is any different than providing it in NYC or SF. Lots of heavy users here too. Sure it is much harder to provide 3G across Canada - but the providers don't have coverage in most of Canada. Even semi-rural areas in Southern Ontario an hour from Toronto have little service.
