I think when you buy a Mac, you're clearly buying the brand. The laptop I'm using right now is the first laptop I've ever paid for out of my own money. I've always used the family's desktop computer up until 3rd year uni. For a small period of time I used an old af second hand Mac that my mum's friend gave her, just to browse the internet before it got too old too use.
So when I was buying this laptop I did as much research as I could. I learned basics like the difference between SSD and normal hard drives, what RAM meant, what a processor was and what difference quality of processor made to computer functioning and so on... looked at the specs of basically any laptop sold in electronic good stores within the $1100 to $1800 range.
The offering of "PC" laptops were broad and came from many brands, which could get confusing. Some I'd heard of - Toshiba, for example (seriously considered a Toshiba touch screen laptop), some I hadn't. But I knew the Apple brand. They had a reputation for good customer service, for moderate levels of reliability etc... Whereas for PC brands - farout. Even if I wanted to do my research, where would I start. I think for me, the extra $200 or so, as an uninformed consumer, was worth paying just to have a central brand that I could 'trust' and not experience buyer's remorse.
(Also, forgot until now, but lower risk of viruses was also a big selling point for me. Growing up I could barely use a fucking website without my Dad lecturing me about TROJAN HORSE MATE BE CAREFUL OF THE FKN TROJAN HORSE DON'T CLICK ANY LINK EVER NO MATTER WHAT ON THE ENTIRE INTERNET OR YOU'LL GET A TROJAN HORSE). Seriously. Trading some GP on RuneScape? Trojan horse. Sending a smiley face on MSN? Trojan horse. Playing Sims/Age of Empires without even connecting to the internet? TROJAN. FUCKING. HORSE.
Anyway. My 2c.
My Mac's 2.5 years old at the moment and still going suppppper strong. Unless I physicall damage it, feels like I could keep using this laptop for a very long time. I'll run it into the ground and probably buy another Mac again when the time comes. (And yeah, after using PCs for 21 years, after adjusting to a Mac, it seems infinitely easier to use, but that probably has something to do with Windows updates since I transitioned to a different OS).
