I currently own and happily use the Apple’s iMac, Mac Mini, MacBook Pro, Apple watch, iPhone 7 Plus (the iPhone X and anything else with the abhorrent notch should have never seen the light of day), and the iPad.
I have no incentive to upgrade like I feverishly did when these devices first debuted. Nor do I have the desire since they are awesome, and the newer devices only upgrade a few features. Apple should hurry and come out with something revolutionary soon or I am going to look elsewhere. I am an Apple fan; but a Steve Jobs fan. but their tech has become stale. Leading edge technology as a whole has appeared to come to a standstill.
If I were Apple I would want roll-out some tech in the areas of quantum computing, augmented reality, VR, and redeveloping iTunes, maps (to rival Google's Ways) from scratch. I would make it super easy to produce a podcast (so that even the elderly could do it) or sell content on iTunes (so people using FCP, or Adobe Premiere, Avid, DaVinci Resolve, Pinnacle Studio, and/or Sony Vegas Pro could easily and seamlessly do so).
I would vastly improve sound quality across all my devices , minimize radiation emitting from all my products, and offer more than the measly current max of GB's of RAM and CPU on my flagship PC's and notebooks.
I would take the iPhone somewhere new such as mind control using emotive (emotiv.com).
You know; innovate and think different.
