Underrated point, maybe it's aluminum unibody or more stable OS, but in my experience average MBP lifetime is meaningfully higher compared to a windows machine. My longest lasting windows machine was T400 Thinkpad which lasted 5 years before Core 2 Duo architecture stopped being able to keep up. It got replaced with HP Envy with great specs but made out of plastic which barely lasted 1.5 years before screen fell off (literally). Replaced with 17" 2014 MBP which is still alive after SSD replacement.
