> Who would weigh themselves down with a high cost phone in your pocket when there's one on the wall?
This was correct. People aren't carrying their high-cost phones everywhere because they want to make telephone calls. They're just called "phones" by coincidence.
People carried actual phones with them long before smartphones existed.
There were carphones which required a big box in the trunk. There were cellphones that did nothing but make calls. It wasn't until much later that mobile phones started doing anything but making phone calls.
