With the Intel laptops, the speed difference was great enough that a four year cycle made a significant difference in my workflow. But the M1 is just so good, I don’t yet have the desire to upgrade for any reason. I don’t even think the M4 would make a dent in my workflow.
@samhenrigold I feel the same way. My M1 Max holds up so incredibly well that I’m not gonna think about upgrading for the next two or three years. It’s still such a beast!
