I just had to ask my boss to phone me back in the middle of a really difficult conversation because I still use a payasyougo 'dumb' phone and ran out of credit... 
I don't have a smart phone, nor does DH or DD, mostly because we fear getting sucked in to 24/7 tech use. That and I don't have an earthly idea how to engage with it all now its all so bloody complicated.
BUT - the other day I couldn't check into a flight before getting to the airport because the only option to do so was via their app....I also couldn't pay a taxi recently because they stopped taking cards in favour of phone transactions....many electric car points require a phone....
Its time to give in isn't it?
