Well, I'll give my point of view on this matter since I use Google Voice quite often. I only use GV for the voicemail feature and to use it for international calling. I didn't choose the one where I get to have a new phone number from GV. I'm still using my regular phone number. I didn't feel like paying Verizon for the extra voicemail feature that they have, so I chose GV's voicemail feature when I received an invite. It works pretty well and has a lot of options for it. The other main feature that I use it for is for international calling. Since it probably has one of the lowest rates, if not the lowest, for international calling, it comes in very handy when I make international calls which I do almost everyday. Just check out their rates online and compare them to others like Skype. It'll show that across the board that using GV's international calling is cheaper. The first time I used the international calling the quality wasn't that good, but over time it has improved quite a bit. I hope this helps a bit.
