I consider the likelihood of needing to repair or extend it within a 6 year lifetime, and I believe the Macbook has by far the best reputation in that regard.
In reality, modern Macbooks have a horrible reputation for repairability and engage in dark patterns to stop you from getting your device repaired even when it is an option.
Counter-point. The company I work for has about 50/50 Macbooks vs Lenovo. We have about 1000 staff, and I've seen similar rates in a company with 5000 staff.
Macbooks
* 2% fail in first 12 months
* 20% need replacing in 3 years
Lenovo:
* 20% fail in first 12 months. (Surprisingly high number fail out of the box)
* 80% need replacing within 3 years
I don't want a laptop that's easy to repair as much as a laptop that doesn't need repairing.
Is that because MacBooks are more tolerant of damages, rather than being resistant? I've seen photos of MacBooks with deformed bodies still operating normally. Same don't happen often with other brands.
