That concerns me. Just not sure where I'd hit the wall. Prev ISPs would show me how many GB I've used in a month, but I don't know that I can get that now. Certainly 5GB would not allow me to sling a movie, but how much surfing would be dependent upon so many different things.
And EVDO isn't everywhere. Take a look at 25419 and select for the broadband coverage on their
map. Looks like there's no broadband there. Not sure what you'd call it, but it looks like it would be about as slow there as AT&T's EDGE. Maybe they use the term "EVDO" for all data connectivity, I don't know, but I think they mean 3G. But it's not high speed everywhere, sadly.
