For many years, I was one of Apple's highest-end customers. I needed the fastest machines they offered for the workloads I threw at them. I made music in Logic Pro with a zillion plugin instruments and effects and I ran a ton of apps with a ton of open windows when I wasn't doing that. I always bought the PowerMacs and then Mac Pro and eventually the iMac Pro when Apple painted themselves into a thermal corner with the Mac Pro.<p>I bought a MacBook Pro M1 Max in 2021 and started using it as my primary machine driving external Studio Displays. It's the first computer I've ever owned that doesn't feel the least bit slow as I approach the three year mark. I've been asking myself when I think I'll upgrade and I truly don't know; probably not before some incredible new software feature isn't available on this hardware. I used to replace machines when the three year AppleCare coverage expired or soon after. I can't see that happening any longer.<p>To some degree, this isn't even about Apple Silicon (though that sure helps). Even my iMac Pro with Xeon processor was approaching a point where I'd have got to this milestone eventually. Apple Silicon accelerated the jump by a good margin. I have no doubt I'd be able to tell the difference if I got an M4 laptop whenever they arrive, but I'd struggle to justify it to myself. (I should mention, in fairness, that I've been on a hiatus from making music since partway through the pan and that undoubtedly makes a difference. But even then, I think the game has changed, at least for me.)<p>I'll keep upgrading my iPhones on a much more regular basis because there's still substantial improvements that I can notice and appreciate (improved displays, cameras, industrial design, etc). I don't think that's going to be the case with my Macs any longer. This will likely be the oldest computer I've ever had as primary when it gets replaced, and I think by a large margin. It's a strange place to be after decades of computing on the bleeding edge.
