"muh GPS" is definitely the most common argument people give me. Garmin still makes car GPS units. I have one and it works well.

To be fair, I was able to refrain from mindless scrolling all the time. But with the phone nearby, I always wanted to mindlessly scroll during every random quiet moment.

I liken it to an alcoholic keeping an ice cold beer on his desk all day, but doing his best not to take a sip. Why subject yourself?

I experimented without a smartphone and I am happier as a result. This will probably not be the case for everyone. But, if you ever feel like a slave to your own technology, I highly recommend trying it out.
