I left my cousin with ArchLinux, he liked it alot, so much that he still used it 6 months later. At that time he wanted to install a new program, well, from then on he stopped using arch. Because he had to call me to help him fix his system, issuing the pacman -S programname failed, so he did pacman -Sy followed by pacman -S programname again, and this time his entire system was about to be updated, he answered yes on all questions... and suddenly his entire desktop was differnt from what it was before. All the programs get updated! He didnt want that!
This is people who think that a computer is broken if the taskbar on the desktop is accidently moved to another position by children. Of course they think they broke thier computer, and it did since their settings and gadgets on the plasma desktop stopped functioning, and some just changed. Without asking the user, just changed! That is a pure and simple WTF. Thats when I realized linux will never ever succeed on the desktop if it doesnt change fundamentally.
