The repairability and durability arguments should apply to HP and Dell business laptops as well, but they largely don't.

If I were getting a new laptop, I'd probably buy a Mac. But if I needed a Windows laptop, I'd buy a Thinkpad (one is currently my only Windows PC). It's not really upgradeable or modular (fixed RAM, SSD and battery not easy to change), but it is well-built and still pretty snappy despite being 6-7 years old.
