I agree. But what's the feature here? I lament the audio quality of cell phone calls, but audio quality depends on bandwidth, and this requires an internet connection, which is going to be spotty depending on location and when transitioning from data to wifi. Every feature here seems a marginal improvement on what already exists (audio quality, UI, sync, security, battery use). No new concepts. Don't get me wrong, I'm happy to use it, but I don't see an impetus for mass adoption.
My understanding is that it has inline content like Whatsapp and desktop support & sync features like Skype (Skype took a lot to make the sync at least tolerable - but I guess they already know what they're doing). The supposedly high quality of the calls and inline 3rd party content support (soundcloud and youtube for now, I suppose) are the bonus features.
