Note: This might not work for your needs if you NEED the core OS to be Linux. It's also not optimal if all the software you need to run is x86-only.

The Macbook Pro with M2 Max comes with up to 96 GB of RAM and a ridiculously high battery life. It comes at the price of... a very high price. And Asahi isn't all that ready IMO, you'd have to run your Linux stuff in a VM or docker container. But for the most part I've found that MacOS doesn't actually stop me from doing anything compared to Linux - the OS is less customizable, but software to run on the OS is still plentyful, especially if you use virtualization or containers (or containers + virtualization).

There's just no real competing ARM laptop out there right now. Not at this performance level. I wish there was, I'd love this kind of performance/power consumption ratio on Linux where I could also eke out more battery life by customizing my kernel. It would be especially awesome if it could be something like a Framework where you can swap out the board for one with a better SoC in 5 years. But for now, the best laptop processors are Apple's.

Thanks to Rosetta, I can also easily run AMD64 containers, so I have access to both ARM and x86 Linux software. The latter isn't as efficient of course. But overall, I feel like there's nothing I can't do on my two Apple Silicon Macs that I could (and need to) do on Linux.
