The average person doesn’t own a computer anymore, but I think steam users are pretty representative of people who want to use the OS that markets itself as “The next generation of Linux gaming”

61% of steam users have 1tb or more total hard drive space.

I think the only thing that will really push adoption is if more systems ship with Linux preinstalled and those laptops are advertised primarily with linux. People aren’t going to go buy a usb drive, figure out how to download an image and how to download and install a flasher and how to use that flashing tool, not when google and apple actively hamstring computer literacy in schools. They probably won’t even click the “budget penguin thing” unless they already know what it is and have been sold the story of linux on that specific laptop.
