Not too long ago, our house was "stuck" with, at best, 1xRTT speeds on our cell phones for data connectivity. Verizon finally upgraded the tower near our house last fall and we've been living in EVDO Rev A heaven ever since. Now, it looks like Sprint is going to be upgrading their towers in our area too, and blanketing the county with more EVDO goodness.

They are not kidding when they say that a majority of the county previously had NO broadband options. No cable modems. No DSL. No wireless vendors (WiMax / etc).
I'm always nervous using the Verizon EVDO service because of their vague terms-of-service that can kill your connection/subscription if they decide you are using too much bandwidth. Thankfully, Sprint doesn't really care how much bandwidth you use as long as you are paying them.
I am hoping they roll out EVDO Rev A like Verizon has. The upload speeds are much better than standard EVDO Rev 0. On most days, I get nearly 150KiB/sec on our EVDO Rev A connection. It also helps that I have a crazy external antenna connected to my EVDO modem and router (the Thinkpad 240 that refuses to die).
