I am neither a gamer or an artist. I don't use my PC as often as I used to because of my phone and tablet. But would I give up my PC? Not a chance in a hell. Somethings are just far too difficult or time consuming on a small device to do. People may not be buying them as often as they used to because even a low end unit these days can do just about anything. But people ain't throwing them away either.
As for stats, I can't give you anything solid, but I know from my own experience (professionally and personally) that almost everyone upgrades something on their PC at some point.
You have a desktop?
So do I, and I've added disk to it but that's really it.
I've just seen the data on PC sales (collapsing) and the move to mobile computing (phones > tablets > laptops > desktops) and assumed with the very low costs ($500) why would anyone upgrade when for a little more they could replace….
