The fact that "everyone" has a mobile does not make this not a problem because, aside from having to figure out which phone to use, this does not apply to people calling into the country long distance. What people don't realize is that the difference between long distance and local, the difference between international and local, is going away.

Except when calling a mobile. It's 3 cents for me to call a landline in Finland, 20 cents/minute to call a mobile.
