I'm disappointed by the amount of ignorance in this thread. A significant portion of folks who use Apple computers don't have to buy them, they are provided by their work, so the price doesn't matter. If you work in software development targeting a Linux environment, almost no one uses Windows. The majority of AWS EC2 instances deployed are running Linux, using apps developed on Macs (a non-trivial portion of the internet that serves content to you).
Anecdotally, I also spent quite a bit of money on a Dell XPS 15 (with OLED) hoping to get a similar experience, and it was a complete waste of money. Wifi drivers barely worked, excessive battery drain in sleep mode, tons of random problems. Windows I guess just insists on updating itself all the time, and breaks things pretty frequently. I was not impressed and gave that laptop away. I know this is just one laptop, but I've never had an experience like that with any of the Macbooks I've owned over the last ~10 years or so.
I guess my only point is that the majority of people that I know that use Apple hardware do so for work, and the cost is not even close to a consideration. I paid $1800 for my XPS 15, and all of my Macbook Pros have been around $2000-3000 in cost, and the utility provided is not even comparable.
"Why are Apple computers so expensive/overpriced?" They probably aren't targeted at you. Do you create media content? Develop software? Make >$200k a year? If not, buy something else..
