I disagree with the comparison of 1XEVDO speed to Wi-Fi speeds. (I always have argued this comparison as invalid).
It it is kind of like saying that while the cable can deliver 1.5 Mbps to your household, the Cat5 cable running from the modem to your computer can deliver 700Mbps! So what! You don't get 700 Mbps on your desktop now do you?
The difference is that 1XEVDO can deliver 3 Mbps to the device. Wi-Fi only gets you 11 - 56 Mbps between a device and a modem (cable, DSL, T1, T3), and the question then is what speed does the modem offer?
The easiest way to get 3 Mbps through Wi-Fi may be to feed the Wi-Fi access point w/ a 1XEVDO signal!
Comparing 3G to Wi-Fi speeds is not an apples to apples comparison.
It would be fairer to compare Wi-Fi to bluetooth, and Cat5 Cable, or other technologies that deliver a signal 0 to 300 feet.
Compare 1XRTT EVDO to EVDV to W-CDMA to EDGE, to Cable Modem's to DSL, to dial up, to T1's and T3's, Wi-Max and Satellite feeds - all technologies that could feed the above category (though some bypass the need to re-feed the device by delivering directly to it).
