Landline Phones
We’ve reached a stage where even homeless people have cell phones. Almost everybody in the world has a smartphone with endless streams of information at their fingertips. But this is a relatively new phenomenon because it wasn’t always true. In the good old days, each house had a landline phone.

This phone had a cable connection and restricted people’s mobility. The signal was also more dependable than standard cellphone networks. But these days, there’s very little difference and most young people never think of getting a landline. Some homes still have them but they’re falling into obscurity (via Dallas Observer).
