Most people don't want to have to use a cmd line to use their PC.
Edit: Seriously, why is it such a confusing prospect to linux users that linux is difficult. Literally, every thread on here comparing distros is filled with
"I used debian, but I had to update it every day or my graphics drivers would fail."
"Oh to fix that regularly occuring issue, just type 'cgreg320 -I1I0O xx /*poweruninstall the year your motherboard was manufactured' into the command prompt."
"Oh yeah, Nvidia graphics cards, AMD motherboards, Steam, Chrome, Adobe products, left-handed mice, and the letter F are unsupported on this distro."
