I enjoy most Apple products, but AirPods were the first product I truly felt were magical. (I also think being a game changer doesn't necessarily correlate with being the best designed product of all-time... just a product that was better than the competition at its inception.)
Macintosh 512K aka 'fat' Mac. Increased memory made it suitable for business use. Built-in Localtalk file sharing, plus the Laserwriter came out around the same time.
