Yeah, but then I have to leave my computer at home on all the time in order to push the notifications. It may be worth it, but right now I don't see the point.
Yeah if Google Voice forwards to your cell you'll get the phone calls to your cell when the app is closed. But like you said, if you only have a cell phone I really don't see a point to the service, since you'll have to give everyone a new phone number that essentially just forwards to your normal cell phone, so why wouldn't people just call your cell... Now if you use the GV Mobile app and make the calls through that it will save you minutes, but that's the only useful thing i can see if you only have one phone line anyways (like I do)
