I'm a 31 y/o Software Engineer, and I have not had a cell phone since ~2004.

It's improved my work/life balance immensely, as my work can't call/email me whenever they like.

The only time it's annoying is (as the article says) when you're trying to meet up with friends and are not immediately and conveniently contactable.

Being that most people spend ~$60/mo on a plan, I've saved right on $6000 - which certainly helped finance my 2 year drive from Alaska to Argentina, and other periods of not working full time to do as I please.

It's crazy when I'm out with friends and they all turn into zombies looking through their smartphones, for up to 10 minutes at a time.

I don't ever want to have a cell phone again.
