The only people I ever see actually using Blackberrys tend to be high-level executives. Why is this?
It’s simple: Because they can get away with it. Only the boss can sit in a conference room twiddling around with a Blackberry, their attention a thousand miles away, while everyone else is working on the problem at hand.
Still, how does this explain the cultural difference between executives and their Blackberries and teens with their mobile phone SMS messaging? Is it only because of the enterprise email integration inherent in Blackberrys, something kids and non-business users don’t need? Or is there some other reason? Is it something about the keyboard-based UI?
