My 12" powerbook from 2002 lasted well into 2011 until I formally retired it by giving to a mate.

Most of my macbook airs have lasted at least 7 to 8 years. None have actually died and were still intact, but I just gave them away, so I don't know how much longer they lasted.

My 2015 macbook pro (pre butterfly) is still going strong today; I did a battery replacement myself which was a huge pain in the arse, so it definitely feels replenished.

I have replaced many of my family members laptops with M-series laptops, nay issue, and I have a feeling they'll easily go a decade, though at some point they'll all need the battery replaced (but I will probably just have Apple do it this time - unless it is easy now with the repair manuals being available by Apple).
