This has *nothing* to do with cash. It has everything to do with perfecting the engineering behind this product, which posed its problems. And If It’s so simple as you noted in your post, then why hasn’t any other manufacturer really developed Apples form of a wireless charger where you can place the device anywhere to charge without a specific contact point like other wireless chargers require? The fact that Apple abandoned this, obviously provided that it has his technical difficulties. Why ANNOUNCE the product if it’s not ready for mass adoption? It’s better that Apple terminated this project versus release something that could potentially have problems or faults that would make them even look worse.
It would have been better if Apple had never announced the Airpower in the first place. So I fixed your question in BOLD
