... oh, screw it, why not say what it doesn't need? It's better for my blood pressure.
It doesn't need Be refugees whining about how BeOS was so awesome and Linux desktops suck. You know what, guys? If BeOS was so cool, and Linux sucks so much, how come BeOS is dead? Now put a sock in it and go practice your OS-necrophilia.
It doesn't need windows users saying "it's not like windows, it sucks". If Linux was just like windows, you would say that there is no reason to switch, so put a sock in it, because you can't have it both ways.
It doesn't need Mac users saying how there's no point working on it because OSX is already as good a unix desktop as there's gonna be, so why bother?. Put a (designer) sock on it, because in order to use OSX you have to buy an ungodly expensive (except the 12" ibook, that's kinda cheap and cute) computer that provides only adequate performance, and I am a cheap bastard.
It doesn't need old unix gurus explaining how there's no need to work on KDE or GNOME because Window Maker is lighter, and all that's needed is a way to keep their xterms sorted. Put a sock in it, because xterm sucks, Window Maker is featureless, and you can't do anything useful for a regular user with just xterms and Window Maker, so you are comparing apples to apple orchards.
Most of all, it doesn't need any "What linux needs on the desktop" editorials.
On other news, I will be speaking about Linux on the desktop at the UADE in Buenos Aires, Argentina, this saturday, and about PyQt/PyKDE programming this friday.
