Well.. for those of us with older non-smart phones, the Verizon Navigator makes sense if you want GPS on your phone. I don't pay for it on mine, but I can see some people paying for it. The versions for the smart phone don't make a whole lot of sense, except that there will always be some people who had it for their old phones and don't want to change.
As for the VVM thing... I don't get the point of VVM or what's cool about it. I don't pay for it and never wanted to go to the trouble of figuring out how to configure the google one. I live without it.. but I could understand people paying for that too if they were interested in it... since a lot of people are lazy like me and don't want to figure out how to make something work if they can just pay for something that just works
I'm both lazy AND cheap so I don't use VVM at all.. lol
