I have been using the GV and Talkatone apps on my Ipod Touch and have enjoyed it, so I bought the Obi thinking it would give some extra benefit. But I can make wifi calls already with these apps when I am away and at home I can use GV to make and receive calls through my land line. My GV rings my home phone when I get a call and when I make a call it rings and I pick it up and complete the call. So can someone tell me what advantage there is with the Obi? Actually, I use GV mostly for texting, which I believe cannot be done on the Obi at this time. I'm sure I'm just overlooking something? Right?
