Read my past post before you get your undies in a bunch. You see, m_stoner, Clearwire and the rest of the industry ARE moving to this technology. It's not a question of IF. It's all about the infrastruture they will have to upgrade on their current systems that will be their hurdle.
In the case of Road Wings, there is no "ball and chain" so they can go in with this right from the get go. No need to upgrade prior systems, no need to satisfiy an existing old technology, no need to spend tons of money for the cross over conversions, no need to support dual systems, no need to create a new business model.... the list goes on and on.
Now, before you go spouting off and showing us all your ignorance, maybe you should try to look at this with an open mind and gain some education.
