I still have a landline but I rarely use it. I guess they're mainly for business use these days and public telephones seem to be on the way out. I've been thinking if your average youngster would know how to use a push button (or even a rotary) dial telephone in an emergency. Are they familiar with the 999 facility ? Do things like this get taught in school ? Mobile telecommunications are here to stay but the landlines, I hope, will always be an important back-up system.
