A really well rounded communications application. I am really happy with the quality of video calls on this one, even when video-chatting with multiple people. The UI is attractive and easy to understand, even for people who are new to smartphones.
Admittedly, my girlfriend would never willingly engage in a video phone call, but perhaps yours is more open to the idea. I use this more frequently to chat with my boys when we miss each other, and we find it works much better than Skype.
