Right now people with landline services pay about 50% of their phone bill in taxes alone (at least that's how it was for me in NY holding a basic line).
What is horrible is that the lost tax receipts gained by the ever declining land-line service will be gained in additional taxes on the internet phone companies. So no matter what, you'll be taxed more, just in a different area to make up for the lost receipts.
I would still be on landline service if it was competitive in price but Americans are being drawn into lower cost services that provide more features. Currently my broadband service with VoIP covers my home needs and I'm happy with the product @ $30 / month.
What is really sad is that even Verizon's FiOS VoIP service has all the "confusing crap" of older systems... Long distance options, regional calling, local calling etc... Pfft... Leave it to a traditional phone company to over complicate a very simple service. Provide dial tone and a flat rate like your competitors!
It comes down to this, if you can provide a better service at lower cost people will buy into it. Sooner or later you must eliminate the old systems and upgrade or you'll end up with the space shuttle boosters as wide as 2 rear ends

As you can see, I'm one American frustrated with how the traditional phone companies have run things over the last 30 years (dont remember back further from that). I'm also frustrated how our stimulus money is being spent. Why not fund the project to get all Americans on fiber by giving grants to companies willing to hire and get people to start laying the necessary infrastructure? Much like roads, upgraded fiber to the premises doesn't only have to be Verizon's doing and it would immediately make the "land line" issue obsolete. Then all Americans would have public "data pathways" and would be able to order whatever internet, phone and TV provider hooked up. Ambitious yes, possible yes, doable in this country, not within my lifetime. Yet overall it would benefit all Americans and would be a good long term stimulation to the local and national economy. In my eyes THAT'S the proper way to rid the land line requirement.
Rant done.
