I used to feel the same way about having a data plan. There's WiFi pretty much everywhere, so why spend hundreds of dollars a year for that small bit of extra connectivity?

Once I got a smartphone with a data plan, it turned out to have a fairly high value in my life. $2/day roughly covers my data plan and buying a new $800 phone every two years. The consumer dynamic is that having the latest phone is worth $2/day.

Dropping $800 recently on a new phone did make me feel something, but it was a positive feeling.
