Apple is the master of the second mover advantage. Let the existing companies burn money in R&D, but closely monitor how customers perceive their products. What pain points exist that the current companies haven't addressed? What are the pitfalls?

And both had bad interfaces (by Apple standards). Apple didn’t show up until they could meet all their goals. They could have made a phone sooner, it wouldn’t have been the iPhone. They could have made a headset sooner, it wouldn’t be the Vision Pro.…
Not enough patents, tbh. It's so hard to innovate and scrap things together, that this gets left as an afterthought.
Then the giants move in and steal your lunch, leaving you with nothing.
