Perhaps the iPod Touch will eventually outlast the smartphone??
I have noticed that here, in S.E. Asia, the 18-30s, in coffee shops, hotels, bars and restaurants, use their devices for social media and photography but never as cellphones. They do not appear to converse or flirt with companions either.
Do those of you living in other continents observe the same habits?
Great observation! Over here in America, normally the high school students ( ages 15-18) and the young adults (ages 19-30) use their phones for social media (2 of the more popular ones these days are Instagram and Snapchat), "professional" phone calls (ie phone calls to the boss of their job), facetiming each other, texting and playing games. The traditional form of social contact has declined due to the advancement of technology. It still exists but not as much as before.
Teenagers and young adults are obsessed about one thing... connection to the internet. Whether it's wifi or cellular coverage [where a data plan and your monthly cellular data usage], it influences how their phones are used over here in America.
One thing that has contributed to the iPod Touch's demise is the standard upgrade path of a iPhone. When one chooses to upgrade their phone through their carrier (Not Apple's upgrade program), often times you'll be able to keep your old phone. These old phones [that cannot connect to cellular data due to the lack of a working Sim card] are often times used as "hand me downs" and substitutes to the iPod Touch. Also, if a younger kid accidently breaks a old iPhone, it's not as big as a deal as breaking a brand new iPod Touch!
