You guys are getting caught up in the details too much. With Wal-Mart trying to compete, WE ALL WIN. They have the retail space and the marketing muscle to make Verizon and AT&T pay attention. And if they start to steal customers coming off their contracts in big enough numbers, the Big Two will have to reevaluate their pricing strategy.
I have read the Dish Network is coming out with cell phones and plans also. We need companies to come to market and innovate and advance the technology. That's the only way customers can win.
