EV-DO Coming on Strong from Sprint
It is possible that EV-DO is actually available in my neighborhood from Sprint. The company announced this morning that it has now rolled out service in "141 major markets and 250 airports." Looking at this map of the bay area I can't quite tell if my house is in the coverage area... but then again I already have Wi-Fi here at home. The important question is, will there be coverage in most of the places I travel to? And it is definitely starting to get there. Here is a link to Sprint's coverage maps so that you can check if your neighborhood currently has coverage.
The 222 airports alone might justify the service, which has "...average download speeds of 400-700 kbs and a peak rate of up to 2 Mbs" according to the company's press release. This is more than fast enough for email and web browsing and would entirely eliminate my need to find WiFi in the airport when travelling. It is even fast enough for high quality VoIP calls, which will definitely be interesting to test.
