A more recent example is the telepresence robot. Many entries, but still more Newton than iPhone.
With Apple, it's easy to pick out their winners and losers: iPhone, iMac, MacBook, ... vs, Apple TV, Lisa, Newton, ....
At their current scale, Apple needs to enter really big markets in order to move the needle on sales and profits. There aren't many really big tech markets left. Cars are an interesting play in that it combines robotics and consumer tech, and puts them into a market that has room for multiple large players and plenty of opportunity for disruption. The transition to an electric drive train and autonomous navigation presents an entry point. There will be multiple winners.
