M1 pro MacBook pro here as well. Just today I was thinking I have no need to upgrade until M7 and by then maybe even MacBook Air would do. Especially since I will have my home server (dgx spark) available for anything serious anyway. So excited for the Mac studio configs though. M5 ultra 1TB would be a huge leap for serious home server builders.

I use an M1 for personal development an an M4 for work. I'm a typical dev. I don't feel any difference.
