I bought an 8gb M1 Air in 2020 (for what now feels like an absurdly small sum of money) as an experiment in how-cheap-is-too-cheap / chuckable travel laptop. I ended up using it as my main laptop for 2 years without regret, then handed it to my son for school. It remains in perfect condition and as delightful to use as the day I bought it (Apple software snafus notwithstanding). I fully expect to get at least 10 year…
Mine M1 Air display just failed after 5+ years out of the blue like worked at night and stopped in morning and even pre-used LCD assembly cost $200-300. So repairing makes no financial sense. Yet considering the price I've paid for it like $0.5 per day and used it daily for 10-16 hours a day. Pretty much like phones I use except I use them much less and drop them often unlike a macbook.
So for me it did make sense to repair - it costs less than a new laptop, at least
