I don't disagree, but even with some unconscious psychological bias, I still think I'd have had some back pain or _something_ creeping in by now after a year even if I was just fooling myself!

Yes it is arguably overpriced objectively speaking, but it is still genuinely well made (although let's not mention butterfly keyboards...)
