25.1% Mac growth. For professionals and enthusiasts, you either just got your M1, you’re saving for one, or waiting on the Pro Desktops.<p>I’m curious to see if there’s any change to the replacement rate of Macs. It seems normal for people to use the same laptop for four or more years — a far sight longer than the two-year life expectancy of laptops twenty years ago, but about half of the replacement rate of smartphones.<p>There's one benefit of these DIY designs that seems under-reported: Apple can now develop stuff like the "neural engine". Chips that aren't just faster or more efficient than Intel offerings, but also <i>do different things</i>.<p>I think there's almost no chance that I'll be upgrading to an M2 Pro next year or the following, but there's every possibility that the M3 Pro won't just be a faster Apple Silicon chip. If future Macbooks are more than just "the same thing but faster," dorks like me will be retiring our computers a lot faster.
