We use multiple M1 airs as dev machines and they're all still working perfectly fine and very fast, nothing has broken, on top of that they were all bought used. We're not looking to replace them any time soon. Not an Apple fanatic personally (don't own a single iProduct), but the M series of laptops is extremely well built and performant. I expect them to last at least 6 years from time of purchase.
