You're not looking at reality though. They are going to lose another 300,000 contract subscribers, this quarter alone. You can't possibly build out a successful WiMAX network if you don't even know how to run what you've got. The problem is that Sprint is now hemorrhaging subscribers and money at alarming rates. If this keeps up, there will be nothing left to spend on WiMAX anyway. I don't think anyone is arguing that WiMAX is a bad idea, but you've got to have your own house in order before you go out and attempt something like this, and Sprint doesn't even know where its house is, much less how to put it in order.

And sorry, but comparing Sprint investors on the WiMAX situation to Verizon's investors on the FiOS project is like comparing apples to beef. The Sprint investors have legitimate concerns.
