FTA has potential to really steer everybody toward VoIP. iMessage got my mom texting and, in my opinion, moved carriers in the US toward the mobile share plans with "free" unlimited text messages. Otherwise, I think iMessage or something similar may have killed traditional text messaging if it had gone cross-platform. FTA has some of the same benefits. It comes with every iPhone using iOS 7. It's also very nicely built in to the OS and reacts mostly like a telephone call. I tried it out a few times once I got my parents' iPhones upgraded. The audio quality is about what Skype is, but the one major drawback is there is about a two-second delay between both parties. I'm not sure if that's a data connection speed thing or just unavoidable lag by using the Internet instead of standard voice connections. But it's a thing. I'd love to hear thoughts from others about experiences with it. I can't stand the crappy call quality of standard phone calls, so I might start using this a lot. The problem is it won't work with people using Android devices unless Apple were to release an Android version. Chances? Not good.
