Yeah the (lack of) difference in price between generations is ridiculous. I just bought a 13 after using my 8 for six years.
The only difference between the 13 and 14 was once graphics core. So there was no way I was considering the 14.
But the 15 has USB C, which don’t get me wrong is great, but when you have a ton of lightning cables that will need to be replaced, it doesn’t seem like such a good idea (especially when family members are still using phones with lightning).
