That's what a successful Apple pivot looks like.
VR, electric cars?! Maybe, but extremely unlikely. Those are obvious things that everybody in Silicon Valley is thinking about and has overhyped to death. Apple would probably take some smaller category that people hadn't thought could hit the big time. IMHO, it's obviously not going to be VR, that's been completely overhyped, sounds cool to nerds but completely impractical and practically useless, and will have basically no impact on the majority of lives out there.
The question is whether the watch repeats the iPod trick of dominating and expanding the market two iterations on. With the iPod this happened when it was no longer tied to the Mac, maybe with the watch that will happen when it's no longer tied to the iPhone?
