I'd actually put forth the claim that if you aren't gaming, animating, or mining, the little mini PCs out now are about $400-500 are perfect for the average normie user. Enough capability to drive a 4K TV for all your entertainment needs (old shit won't cut it here), plenty of ports, ram, an extra drive slot for more SSD space, and of course it works with all the office products just fine. Could even use some engineering software no problem. And these little bastards handle old games just fine, to be honest. $200 isn't really enough, it won't have the CPU/power for 4K - you really do need a few more bucks for faster shit.
Anything less is gonna be a pain for a normie in some shape or form, be it incapable with current monitors and TVs, or just being a slow piece of shit. They even shove these into monitors too!
Though technically tablets and phones are at the point where you can "adult" from them just fine, and phones especially with the new 2 step validation every shit does. They just cost a pretty penny compared to the other options.
