Another who hasn't had a landline for approaching a decade and haven't missed it for a second. For those nervous about the thought, in all that time I have never once been unable to make a call from my mobile.

Slightly different topic but related to the need to have a landline for the Internet, in my former home (rural Gloucestershire) I used the various 4G services as my internet solution. In my current home (nearer to central Cheltenham) I now use Vodafone 5G for my internet.
