I think I got my first cell phone only about 15 years ago, when I bought a bare bones at&t flip phone. It still works, but about 8 years ago I passed it on so my mother could have a cell phone, and I replaced it with a new version of the same model.
I'm not sure what experience you want me to share...I think my husband's smart phone has a great camera, and on the rare occasions we road-trip, it's useful for navigation. But those features aren't enough trade-off for the very high monthly cost and the constant connectivity (which I don't like), so I don't pine after getting one myself.
My phone is a phone and a 'watch' for me. It works fine as long as my carrier has towers in the area. I have had to replace the batteries a few times over the years.
