A few days ago I made the leap to cellular wireless data, hoping to live the dream many of us have of trading anywhere, anytime. I'm unhappy to report that it is not yet ready for prime time, at least by my experience. I contracted with T-Mobile for a wireless PC card for my laptop. Connection was no problem, but the speeds are less than 56K, and not stable. After further research, I'm of the opinion that other systems have similar problems, and it is not a problem with my vendor or card. The promises of the providers are not yet paying off in reality. Hopefully WIFI will soon become advanced to the point where we can enjoy broadband speeds nearly anywhere. But until then, wireless isn't worth the bother.
