I no longer have a landline, but I miss it.
Ours was a traditional wired line, but some years ago the service got more unreliable than my cell, and much more expensive then it had been. The phone company no longer services the lines and our cell service had improved rurally in the meantime. I just couldn't justify the expense for the unreliable service any longer.
But if it had remained reliable and affordable, I definitely would have kept it.
