The only thing WiMAX has is Intel. This thing will go the same way at Earthlink's 802.11 experiment in Philly, canceled. If anyone wants mobile wireless, EV-DO or HSDPA is what they will get from their cellular provider.
It's is a shame but I have seen it before. I worked at the startup that invented 802.16, now WiMAX. Bankrupt. I worked with several other promising new technologies, all gone. I am sure my friends at Intel and NextWave will be calling me soon looking for employment leads.

#1...Yeah, Vaporware that will cost on the order of hundreds of millions to fully deploy, with working hardware and test networks set up.

It's not that it's vaporware...it's the classic chicken-and-egg scenario. In these semi-rough economic times no big corp wants to invest in a technology as the customer base may or may not accept.

Considering only sprint is rolling wimax out in the US. LTE would be the better tech to have in a pc, as it will be supported by Verizon and ATT

Nice fancy shmancy feature, but what is the monthly cost for the service and are you forced to use a specific carrier?

[Asus] eventually decided that the WiMAX market "will not reach maturity in 2008."

If it ever does. Wasn't intel's Barett promising that wimax would be the solution to "USA's half-assed broadband" by 2006? At this point in time, perhaps it would be accurate to draw parallels between "internet over the power grid" and wimax. In terms of both being extremely hyped technologies which have time and again failed to meet expectations, or see wide deployment. Not exactly vaporware, but close.
