I suggest they fix crashes first (happens regularly to me on iOS, Android and OS X), and just then they start adding features. I can't help it, but before microsoft bought the Skype, I barely seen it crash in years. But now, a longer call hardly goes by without crashing either on my or the other end. As much as I hate sharing my camera and microphone with google, I slowly migrate to hangouts -- not because I like, but because it doesn't crash.
If that is true, I guess the mother nature is far more advanced than I could even imagine. Sonar, ok, infrared sensors, ok, antibiotics, ok, aero/hydro dynamics, ok, but electric field communication, wtf? I thought this domain solely belonged to human race.
