Need to get a Sprint or Verizon wireless broadband card

Any thoughts on which one to get? I’d like to have a more consistent Net connection when I travel. The hotel where I’m staying at, the connection was awesome on tutorial Wednesday, slowing down and hiccupy on Thursday, and stone dead on Friday. We’ll see what its like this weekend, but I think there’s some sort of inverse correlation between the network reliability and the # of RailsConf attendees playing World of Warcraft, so I’m not optimistic. Well at least the wireless at the conference itself is pretty stable.

I’m currently leaning towards the new Sprint card that goes into my MacBook Pro’s ExpressCard slot, the Merlin EX720. Anyone love/hate this card + service?
