Okay, so here's what I don't understand about Apple not providing a power brick this year:
The rationale is that most people already have them so it would just create more waste... Okay, that makes sense. But the cable they're packing this year is lighting to USB-C... Don't the vast majority of iPhone and iPad owners probably have USB-A charging bricks that came with previous devices? Only people with iPad Pros and certain model Macbooks will have a USB-C charger.
I'm hoping that the iPad Air 4 will be available before the iPhone 12, and I intend to get both, but if the Air doesn't come first, I don't own a single USB-C charging brick.
