Verizon EVDO

I've been hearing people (online) talk about EVDO a lot lately, like Verizon was just rolling it out. I'm not quite sure what the deal with that is, as Verizon has had their EVDO network deployed in a bunch of metropolitan areas for quite a while now. I'm not sure why people are just noticing this now. Too expensive for me though...and I'm a Cingular customer anyway. Too bad I don't have an EDGE phone.
