And why not have a home phone? Of course I have a cell, but when I have an important matter to discuss with anyone I use a land line and I am never disappointed with it's clarity. I am handling an estate at present for a very wealthy client and he has specifically asked that I always call his land line with mine. Certainly if I could only afford one, it would be a cell, but if that's not an issue, why not have a land line home phone?
I got rid of my land line and replaced it with VOIP from Comcast. It has all the advantages of 911 as a land line but much cheaper. The only disadvantage is if your cable goes out--then you lose it.
