Bingo! Nobody needed color tv, but some found it more enjoyable than blank & white. Nobody really needs a cell phone, but they tend to be more useful than land lines. Thankfully most people like innovation.
That's debatable. Yea, cell phones can be used wherever you happen to go to, but they sound worse than landlines, drop calls, don't always work (or don't have nearly the "uptime" that landlines do), and you have to remember to keep a cell phone charged. And the internet service on cell phones is outrageously expensive and limited compared to DSL.
