I'm 30. I got my first cell phone when I was 25. That flip phone just broke and I had to get a new one.
I liked the "idea" of a smart phone for being able to look stuff up when I needed information, but I hated the idea of paying for that.
Then I found the Kin TWOm. It is a regular feature phone from Verizon, but it has wi-fi. No data plan required. Obviously I can't look stuff up at anytime, but free wi-fi signals are all over the place. And my monthly bill is extremely cheap. Oh, and it has the QWERTY keyboard, so texting is easier than with the traditional 9 button key pad.
In general, I'm a bit of a luddite and I'm really not that into tech. But I must say, this new phone is pretty cool.
