Number one is because they’ve patented the trackpad sol noone else can use the newer style. Number 6 is madecompletely moot by the high price and the fact that many other vendors have laptops with BETTER build quality. Especially if you factor in all the engineering missteps they seem to constantly make.
Doubt me? Just look up Luis Rossman teardown videos. He’ll show you actual macs from customers, that he takes appart onscreen, and shows you exactly how Apple makes extremely basic engineering mistakes.
Don’t like him? Look up anyone else that gets under the hood of Apple products without being in Apple’s cultish parts program.
