I wonder how many people like I don't really find my land line all that useful anymore. I question why I pay $20/month for something I don't really use that much. When you have a cellphone, SIP, Skype, and you can even call on Twitter it seems like it is enough. I was told that even after you cancel your land line 911 service tends to continue to work. Tempting to save that money. Internet connection is invaluable, but a landline and cable TV isn't for the next generation.
It makes me wonder if Google Voice lets you transfer your land line, to a free Google Voice that then transfers the call to Gizmo which the bought, how many land lines will be lost? Cellphone only households are at 18% already.
