Which Line 6 Pod should I get? 2.0 or Pocket Pod?

First of all, I'm guessing I'm not missing out on much if I decline a pod XT if all I'm going to be doing is a lot of heavy distortion and some wah pedaling, right? The Xt just has like twice the amps and stupid effects and stuff like that I think, correct me if I'm wrong. If that's right, then I'm deciding between the pod 2.0 and pocket pod. From the site, it looks like they're the same exact thing, except the pocket pod is more portable, has more presets by actual artists, and has a USB connection unlike the 2.0, and no other drawbacks to the 2.0, is that correct as well? If so then I think I'll just get the pocket pod since it costs less and would be fun to take places and play on headphones.
