ZDNet's Russell Shaw says the interplay between EV-DO and Wi-Fi "will affect the near-term prospects of broadband wireless."

With a Sprint EV-DO-enabled HP notebook, Shaw tried keeping up on his work while on a train, but found that "EV-DO has blind spots. And during those blind spots, you wind up going offline."

Bottom line, Shaw says, "I'm glad my notebook has EV-DO AND 802.11g Wi-Fi capability. Props to EV-DO: ideal for when you are on the move, and flexibility of adding on whenever and to a growing extent, wherever you want. Props to Wi-Fi: ideal for filing when you are going to be at one place for awhile."

Or, as a reader replies, "Just give me my WiMAX."
