- Display was replaced under warranty after 2 years due to ghosting
- Upgraded the 256GB SSD to a 1TB model after ~5 years
- Had the battery replaced by Apple store after ~7 years
- Mainboard was damaged by Apple store (USB no longer worked after battery replacement), after a lot of back-and-forth they replaced it under warranty
So I'll admit, not much of the laptop is still original, but the fact that I can still daily it for my development workflow is impressive. This thing just won't die.
For work I replaced the MBP with a Lenovo X1 Extreme, partially due to the praise of Lenovo here on HN. The total investment of the Lenovo was higher than the MBP, but I was planning on doing another 10 years with the Lenovo. Though the build quality is OK-ish, but I have never been satisfied with the it. Linux support (the main reason I bought Lenovo) is rather bad, the laptop gets very hot, fan noise and coil whine make it annoying to use. The battery completely died after just 2 years, and Lenovo could not supply a replacement (they actually recommended searching on Amazon for a aftermarket replacement!). SSD died after 3 years, luckily they are replaceable. One fan died after 4 years, had to source a used one from ebay since Lenovo no longer offers replacement fans. Had to replace the thermal compound on the heatsinks twice due to the laptop starting to overheat and shut down.
I know, I know, sample size of one and YMMV, but I don't think I'll buy another Lenovo laptop after this one.
