We have a landline and wouldn't be without it. In the case of long electricity cuts, which we had in our area a few years ago, a landline was a Godsend. Also we still keep an old "plug-in" landline phone, because when there are electricity cuts, the "wireless" landline phones cease to work. DH & I both have smartphones but we use the landline a lot, including for long family calls. Our smartphones aren't always switched-on (we aren't slaves to them, unlike many smartphone owners) so for us the landline makes life easier.
