Apple still sells a megaton of stuff, and I’ve never been in an Apple Store that wasn’t packed.
That said, each iteration of Apple products is a little less appealing to me, and there’s no way I’d buy an iPhone 7.
The new products don’t seem well thought out, from an ergonomic standpoint. That was always Apple’s big strength.
I have an early 2015 Macbook Pro that I really like. And an iPhone 6 (the normal one, not the big one). I have no incentive to upgrade either one. If my phone was a 5, I would consider a 6 or 7 but there is no compelling reason for me to upgrade either item at this point.
