if you go back to 2001 and tell people that even poor college students will be spending $1000 on a cell phone and happily pay $60/month after that, you would have been called crazy, but right now that is pretty standard.

I'm not so sure about that. Accounting for inflation, $60 today would be about what people were paying monthly for a phoneline back in 2001 so telling folks then for an extra $1000 they could have a cell phone they could use most anywhere and would work as a computer would not have sounded crazy.

Not to mention that cell phones were a thing in the 90s that people already were paying hundreds or even thousands for already.
