So I'm a bit ignorant about the mobile phone industry. So Im trying to figure out what makes a power user. I figure it is some that lives and breaths with their phone. BUT I would like to get more precise. Like does it include:

• The 16yo who sends 100 sms's, plays games and listens to music all day?
• The corporate lackey who talks for 4hr / day, does email and schedules meetings etc.
• The techy who like to code on their device

We use this terminology all the time but im curious what it really means. cos imho they are all "power users" in different ways, and the first example is probably the most intense user out of the group, but, i think we often forget about him.
