Proud flip phone user here
. It used to be because of cost, but now I'm a conscientious objector of sorts - best way to teach my kids they can function without a smartphone is to function without one myself. (Also I don't trust myself with one.) I used a Motorola Razr for over a decade, till they quit supporting it
. (I had great fun ironically bragging on my phone as "the cool phone of '05"
. It was an awesome phone, though - I miss it.) Now I have the cheapest-phone-they-carry that they gave me free to replace my Razr.
