The Apple Watch was absolutely revolutionary.
Sure, it took a few years to get there, but I don’t think there’s any denying that by the series 4 the thing had become apples second most impactful product, only beneath the iPhone.
It wasn’t the first smart watch, but it certainly was the first to do everything well.
Same goes for AirPods, while them in isolation as wireless headphones weren’t necessarily that revolutionary, they were the first truly wireless headphones that “felt” like something people wanted to use and not a cool gadget for nerds who didn’t mind dealing with pairing menus and pin codes and terrible device switching
The Watch and AirPods are both great, but I don’t think they approach the category of the iPhone or the Mac or even the iPad in terms of the world being dramatically different after their introduction. Those products completely changed the world.
