I'm kind of glad I didn't have a cell phone until I was 23. That's right around the point they became really mainstream, not just for the business types or the heavy telephone users.

It definitely feels like most people inherently tend toward having difficulty moderating their use of any technology that has a tight reward feedback loop. I think the interesting question here is whether giving kids a mobile phone enhances their psychological 'immune system' as an adult, or whether it just instills these patterns of almost-addictive mobile phone use earlier on at an age when it's more important to be learning basic facts, developing critical thinking skills, and developing creative ability.
