From my experience (and I know it might be skewed a bit), most developers that I know or have worked with, if given a choice, prefer MacBooks (at least for backend/frontend/Android development.)

If people are actually using ARM for development, it also makes sense to use ARM for CI and production servers, since maintaining support for two architectures is just not feasible in the long run.

Recently, I've been testing ARM on CircleCI, and in my experience builds and test runs are about 20-25% faster on ARM vs x86, which to me seems like a big win.

What do you mean when you say "test runs are about 20-25% faster on ARM vs x86"? Are you comparing similarly priced systems, specific processors, or what?

CircleCI offers machine executors, which I assume are basically just EC2 instances (in the past they were hosted on GCP), and for example using 'large' executor has the same per second billing, but large ARM instance is ~25% faster than large x86 instance.
