Definitely my smart phone. I only acquired one, about 6 years ago. But I use it for everything. News, weather, entertainment, porn, phone calls, email etc.
I could live without it, but it is very convenient. Especially with Google. My family bought a set of encyclopedias, back in the 90’s. They used to be a treasure trove, of knowledge. Now, they are practically worthless…
These smart phones, replace cameras too.
Mine, has a compass, tidal charts, Google Earth, a guitar tuner, Pandora, YouTube, any number of streaming services, star charts, a calendar, a calculator, an alarm clock, GPS. I could get more, if I wanted.
It’s an amazing device.
