I remember looking at pc sales data, and they have been shrinking in the last decade, with the curve flattening until the pandemic, when sales grew substantially, almost to the 2000s level. Now it’s shrinking back slowly. I’m not sure if people are abandoning desktops in favor of phones as much as we think. desktops are durable and we tend to have only one, while mobile devices are gaining different forms, and people are getting more of them. Perhaps the desktop market has not much more room to grow while mobile devices are still booming.
But that’s just one possible explanation, I might be wrong. I was going to post the data, but statista requires login to see it.
