Biggest things make great news. Companies create visionary ads. People get excited. People go out and buy stuff. Increasingly, the promise of the ad and the reality of the product and service don't match.
People get disappointed.
People get jaded and cynical. Accessing the Internet with my computer can be frustrating. Accessing it over a mobile phone sounds like too much hard work. Maybe there is information that I simply must have while on the move, but right now I'm not aware of it. I'm rarely more than a few hours away from the ability to access the Internet through my computer.
