I have CLEAR to use when I travel for work. I was in Raleigh/Durham a couple of weeks ago and you would swear that it was a totally different network than we have here in Dallas. It was blazing fast, never dropped me and extremely consistent. For what I use it for, it works fine. Even here in town, it's not terrible. However, all of the other options mentioned here are probably better alternatives (with the possible exception of 3G).
