If your goal is to sell more MBPs (and this is marketing presentation) then, judging by the number of comments that have the phrase "my M1" and the top comment, it seems like M1 vs M4 is the right comparison to make. Too many people are sticking with their M1 machines. Including me.

It's actually interesting to think about. Is there a speed multiplier that would get me off this machine? I'm not sure there is. For my use case the machine performance is not my productivity bottleneck. HN on the otherhand... That one needs to be attenuated. :)
