I have a landline because I’ve always had one. It is however a VOIP line. It does ring on my iPhone which my son gave me because I refused to go to the dark side and get a cell. His logic was once I turned 60 I must be on the verge of falling down and not getting back up.
Thinking of dropping my current landline and keeping my internet, then signing up for a VOIP account (maybe Vonage). VOIP appears to be much cheaper (about half the cost) and I'd still have a landline. Don't get very good reception on my cell.
