DS14 has an IPhone 5s which is on its last legs and he's making me feel stingy (which I mostly ignore) in not considering getting him an iPhone 6s as a replacement for Christmas. I was thinking along the lines of an iPhone SE!
To make it worse, I asked 2 (less well off) friends with similar aged teenage DC and both admitted that their DC had an iphone7 last year! So, if your DC are teens and are getting replacement smartphones for Christmas, what are you buying them? Otherwise, what do they currently own?
