> I don't believe most people use a tablet/phone as their primary computer (though maybe their primary web surfing device).

I may be too pessimistic, but I think most people use little else than browsers and apps to access social networks, mostly from phones and tablets.

https://www.statista.com/statistics/273495/global-shipments-... says about 275 million PCs shipped in 2020, https://www.statista.com/statistics/263441/global-smartphone... 1,280 million smartphones. That’s almost 5 times as many, ignoring about 40 million tablets per quarter (https://www.statista.com/statistics/272070/global-tablet-shi...)

Some of that will be because smartphones last shorter than desktops, but It wouldn’t surprise me if half the smartphone users didn’t even have a desktop PC.
