I (an Apple fan) do not consider this a failure. I love it when companies take chances and go all in on pushing the envelope. Great products do emerge from these sorts of products.
and i personally feel this failure is an indication that their product line isn’t as streamlined and consistent as they market it or they’d like it to be. because this is a wireless charger, which has already existed on the market for many years. so why did the airpower fail or why is it so different from the others? well, for one, it was trying to charge three different types of devices, which probably complicated their solution.
and their response is typical apple. it seems they actually couldn’t make it work at all or pass standards, not this idea that they have every going good but it doesn’t meet their “high quality standards”.
