the many ways of the Telephone

as a kid I use to have the Phone rotary style&then the Press style. then the Phone in the Car. then you have the long cord Phone where you drag the line all over the House. then you go cordless. I mean the Phone has gone through so many ways to use it. some folks use headsets to operate when they are talking. nowadays you can talk on a Computer directly but upon thinking back in the day wow we have gone through so many ways of using a phone.to bad a Pay Phone ain't adapted to Modern Technilogy yet though?
