I also don't think they know where the technology will end up or what they really need to do to make it a truly useful, indispensable mass market product. But they expect to learn and find out over the coming years. Like they did previously with Watch.My theory is they’re trying to get developers and content for the device so when the technology gets to the place where it’s at “iPad Pro” price points there’s already an ecosystem there.
Some on here disagree with me about that, and of course it’s possible it never takes off with developers/content creators, but that’s my story and I’m sticking to it.
