iPhone 15 looks to be a pretty great update, at least for the Pro. Personally I have been holding out for a USB C iPhone so I was going to upgrade whenever that happened but there are some other things that look good as well.
I recently bought a 67W charging brick with 2 USB-C slots and I’m so happy with it, I’ve had the same experience of being able to charge any device I use with the same USB-C to USB-C cable: from MacBook Pro to iPad Mini (love it, it’s just the perfect size), also the Steam Deck and Nintendo Switch. At this point I hate having to go grab the lightning cable specifically to charge my iPhone
