Remains to be seen if the new phone is ~$1500 CAD better for me.
That it won’t be. You’d just have to stomach the price and tell yourself exactly why you spent that amount.
For me, it was a combination of lowest ever price on the 12 mini, the time (I would have upgraded next year anyway) and the display - when I saw it in person, I just realised how much better the contrast would be for my father’s old eyes. I just got one for myself along with because of the price and because I knew father wouldn’t like it if I kept old tech and he used new (I’m his child, he knows my fascination with tech).
