Actually owning your laptop instead of being locked in a garden/prison managed by a soulless corporation is a must for me.

macOS is open.

  Notably MBP benefits don't matter much you're using your laptop as a mobile workstation. People love to boast about Mac's batter life, but my Framework is set in BIOS to 60% of max battery life because 95% of the time it's standing on a stand, plugged to an external screen and keyboard&mouse. As a developer I need a proper chair, split keyboard, good posture, if I want to make it to the old age with this lifestyle. Laptop form factor is for this 5% of the time when I want/need to work from somewhere else than my desk.

If battery life doesn't matter to you, then surely speed does right? M4 Pro is roughly 56% faster in ST and about the same in MT.

  Also, if you're a developer there's a lot of perf loss and impedance mismatch with Linux ecosystem (like x86_64 emulation) on Mac.

Even after emulation, Apple Silicon is often still faster. The fastest Windows laptop is actually an M4 Max running Parallels.

  So Framework is kind of a Linux dev go to machine ATM. Different priorities. For others ... yeah... a nice appliance like MBP might be a better choice.

Agreed. I think most people prefer macOS as a dev OS to Linux.

  Oh, and the biggest advantage, is that I can replace a lot of stuff and not need to lose my stickers!

Framework's parts are known to be very expensive. It's probably cheaper to simply sell your Apple Silicon laptop (which always has high resale value) and simply buy a new one.
