I have a smartphone that was a hand-me-down five years ago. I use it when I travel. I have a landline for home and office. On a recent journey, I discovered I needed to recharge it far more often. I suspected the battery was going. And so, as soon as Julie arrived by plane, we headed to Verizon. Buy a phone myself? No chance. Julie took care of all of the data, etc.
I bought an 8. Anyone who knows me should be surprised.
