because most windows "laptops" are flimsy plastic pieces of shit that insult you with pre-installed crapware, built-in ads, trash battery life, overheating, and low grade parts that burn out after a few years. Even expensive "gaming" laptops are trash. PCs are low-profit commodities now so the companies just try to out-jew each other by ripping the consoomer off
macs certainly have their flaws (it's apple's way or the highway) but at least it feels like they are trying to build a respectable product to earn your money. They have been excellent since they dropped the intel chips and switched to apple silicon
only way to get a non-slop windows machine is to build a desktop or get a business laptop
