I disagree. Nobody outside the tech community knows that Google Voice exists, let alone how to use it. This has solid branding (esp. the name) and good messaging.

The price might be a little high for what it's doing, but if the idea is to eventually phase out your landline number, this could be a good way of doing it.

I had to login just reply to this... Google Voice is used by all kinds of people. I can think of at least ten people over the age of 50 in my family alone who use it. Hell, my 81 year old grandfather has a GV account that forwards his old landline to his cell.

Almost every one of my non-tech friends uses it as well.

Did your grandfather set it up himself?
