Iden is being phased out. Sprint is introducing a new technology today will offer same benefits as current push to talk phones. But now they will all include high evdo speeds and better coverage. Just look up the new sprint vision initiative that sprint introduced a couple months ago. I think it also included a slightly faster 3g speed by introducing the next level of evdo. This way as they make the changes necessary for lte people won't be too mad.
Right now its not that bad. I think most people use 4g when they travel and tether to their laptop or tablets. I only use 4g when I'm at a hotel due to the fast battery drain. Right now all 4g phones including verizon are battery hoggers.
