> It's like landline telephones. For people with established land line systems, the value of a cellphone isn't that much.

I get what you're saying but...this just doesn't make sense. If this was true, how do you explain the now ubiquitous usage of cell phones? Neither I nor any of my (in their 20s) friends have a land line, because we all have cell phones.

Places with really bad landline systems generally got much faster and more widespread adoption & growth of cell phones and mobile services (such as mobile banking, etc) than the advanced countries.

Now cellphones are everywhere, but pre-iphone era USA was rather backwards in terms of mobile phone usage. Also, "majority of young people being mobile-only" was an obvious thing in many much poorer places long before USA. None of the people I know in their 30-ies have had a landline for more than 10 years now - as far as I remember this was not the case in USA back in early 2000's.
