Microsoft has definitely put a lot of work into the arm surface laptops. I'm having a good time using a surface 15 inch. I picked the lowest spec model, only 16 GM ram and 256 GB drive. But I use it like a terminal: I run vscode server on either my desktop or a VM, and the vscode client on the laptop. So the actual compiling and I think also the LSP is running remotely, but I still have a responsive editor on the client. The result is phenomenal battery life, 16 hours if not more. It also has the side effect that any build artifacts are produced directly on the server, no more uploading multi-gigabyte containers over my home Internet to the cloud. But of course, it assumes 24/7 internet connection.

I would appreciate a native Linux arm laptop, but this setup works for me in the meantime.
