This is also true of every ThinkPad Linux system I've used over the last fifteen years, as the ThinkPad is as close to first-party Linux hardware as exists. It's also true for the majority of Windows laptops in the MacBook price range, I assume. I'd also assume that Hackintoshes don't work as smoothly as you describe, which feeds right into the parent commenter's complaint.
The parent commenter just has higher standards than you: either that software and hardware are relatively easily decoupled and should be, or that laptop manufacturers should competently implement the standards they claim to, or even just that he's never worked at a company whose product was as poorly-made as almost every laptop's compatibility software.
