>30 seconds vs 3-4 minutes on my previous laptop (14" M1 16GB) is a big deal. It was more constrained for memory (swapping) and CPU and just ran a bit slower. Still reasonable. But a 7x improvement is massive for me. Times 10 or so per day adds up to really significant time savings. If you compile stuff, run expensive test suites, or whatever: you could use a fast laptop.

This was in their original comment. So, when you say they are only arguing cost, I really have no idea what you are talking about.
