Good insight Pekkle. Kind of what I've always thought. And you can tell who cares about educating themselves (if only with public 'outsider' information) and who is just there 'cuz its their job.
Not unique to the cell phone industry. I'm a "car guy," and I pretty much always know more about the car than they do, kind of like most of you guys and phones. It cracks me up when car shopping how salesmen will just start taking about a car, usually knowing nothing about it and almost alway knowing nothing about competing cars they're trying to talk out out of. If they're arrogant about it, it's always fun to ask them about gear ratios or something like that, and see them try to explain it.
If they just want to show up for work, that's fine with me, but don't act like you know something.
