It was in the car of course, like so many other American activities, and only five years ago if memory serves me. I am talking about sending my first wireless email message. Wireless email was supposed to be the application that primed the wireless data pump, but instead we were all just sucking up lots of hot air. The wireless data universe continues to expand, with more choices for wireless carriers and devices. First, let set expectations.
Wireless data is neither a cause nor cure for cancer.
Wireless data is slower than wired, there is no getting around that. You want to surf the net at T-1 speeds, find a wire and jack in. Wireless is still painful to implement, mainly because you are your own integrator and have to put the pieces together. That hasn't changed in five years, and might never change. If you aren't the type that gets off on seeing miles of aisles of different plumbing fixtures at Home Depot, then find someone else in charge of your wireless pilot program.
