If that had been what you said in the first place, then I wouldn't have said it was ignorant. You said that WiMAX is vaporware, not that it has not yet become widely enough deployed in the US to replace cell phones.

The fact is that it is not vaporware, it is widely deployed in some regions, and it is deployed in some markets within the US. It is clearly not vaporware, by any stretch of the imagination.

But, you're right, it's not yet deployed widely enough within the US to be a replacement for cell phone service. That, however, is not a reason to think that an unveiling of the WiMAX NIT at CES would be premature. Especially since there's going to be a WiMAX presentation at CES.
