EV-DO has lower spectral efficiency, suffers from the near-far problem (a slow users screws everyone else up) and worse of all, has significantly higher latency. Try playing everquest on an EV-DO network.
the "FLASH" in FLASH-OFDM is not the same as the "flasl" in "flash memory." From the description on the website, it looks like you will have to get a special PCMCIA card (similar tot he card you have to get from Sprint to use Sprint PCS Vision).
Magnus - Flash OFDM is significantly better than EV-DO. It has lower latency, higher spectral efficieny, and does not suffer from the near-far problem.
It handles doppler effects well and as a result woeks really well in cars. Imagine having a broadband connection that you can use at home, take it with you when you are in the car, use it when you are at the airport or anywhere else for that matter.
Verizon's EV-DO based service (currently available in DC and San Diego) suffers from what is called the near-far problem typical to CDMA networks. While the bandwidth seems adequate today, as more and more users get on the network, the overall performance will degrade rather quickly. Users further away from a base station will have to emit at a higher power level to maintain their meager connection speeds, and that will force users close to the same base station to lower their power emission, thereby lowering the effective bandwidth seen by them.

i suspect it is that latter. i is easier to deal with the users of the most dominant (evil) os during the trial period.
