If we had real sales people wearing out shoe leather trying to get a foot in the door, long ago we would have realized that our superior operating system is only superior to computer savvy users who are able to fix what they break and configure what they buy and who have the patience to figure-out things like why a configuration made in the KDE UI disappears at reboot. Hint – it might be because that particular configuration in your particular distro must be made in the distro’s configuration panel which overwrites anything done in KDE’s panel, even though it’s a KDE configuration. How many grandmothers will figure that out?
