"BUT----I STILL have a landline phone in my residence. Because I WANT one. I still have a use for a regular land-line phone."
You still can. Sort of. The phase out doesn't mean everyone has to go buy a cellphone. For all intents, you won't notice any difference after the switchover. Pick up the receiver, still have a dial tone etc.
One drawback is that the old landlines supplied their own power, so that if the electricity went out in your home due to a storm or something, the phone generally continued to work. With VOIP, if you lose power, you also lose phone. That could be bad in an emergency for those without a backup cell phone.
But, I just did a quick mental inventory of all the elderly people I either know or who are family members. I could not think of a single person who doesn't have a cell phone. I would think the number of people who rely solely on a landline must be an extremely tiny percentage.
