To this day I still dont know why people worship Apple Silicon. Before it was even named and was mostly used by iPhone as A10, A11 and A12, when I stated these CPU are Desktop grade all I got was being laughed at. But then when it was put into usage by Mac using the same chip now known as M1, M2 etc. All of a sudden they are gold.
Apple did at one point has the leadership of PPW ( Performance per Watt ), but since then competitors have catch up. Qualcomm Oryon and ARM Cortex A930, even exceeding Apple if you look at other metrics. ( We will see what A18 has to bring us ).
-> the smoothness of the Apple trackpad
Because no other PC manufacturer is willing in invest into it and pay for it. For example speakers, it wasn't until Laptop reviewers paying attention and start saying how awful all the PC Laptop speakers were when compared to a MacBook before they started to improve. While Speakers were easier as it is low cost item. Trackpad isn't. But it got much better when Microsoft decided to invest into the PC ecosystem and Surface Laptop, so other PC manufacturers can take advantage of it. It still isn't quite as good as the one on MacBook. But Surface Laptop is pretty close, or may be just different as some would argue. Similar to Keyboard where Surface has the old MacBook 2015 scissors keyboard with better Key Stability, I value that as better than every keyboard that is currently with Apple.
