Every time I've priced out a laptop with similar configuration to my MBP (including a good-quality display, NvME SSD, good battery life), it always ends up costing about the same as an MBP. And then Apple's customer service definitely tips in their favor (I've been spoiled by fast, convenient, competent repair service at the Apple store).
So either everyone is making big margins on well-configured laptops, or the perception of over-priced MBP's is misplaced.
