But most important of all, it allows you to look at the "Future Ex Wives" thread while on the crapper. I mean, why would you NOT have a cell phone.I’ve used Apple Smartphones since they were first introduced. When I was working, I carried a Beeper 24/7 and had a Carphone installed in my truck. When Smartphones arrived, I shucked the Carphone. Smartphones provide direct telephone communication via speech or text, document transfer, research, word processing, document files, education, videoconferencing, calculators, mapping and gps, photography, video information sources such as YouTube, audio and audiovisual entertainment (Netflix, PrimeVideo, Max etc), access to forums (such as this), shopping, selling, tracking, access to emergency services, and so on….. Smartphones offer a lot more services and conveniences than the old PDAs and they are a lot more comfortable to carry around than a notebook or laptop pc. One would require a mobile office van to provide the features that a smartphone can offer in your pocket.
