Debian has deb packages which works like readymade click and install type. I have not installed any software in Ubuntu or Debian by compiling.An honest question, why do people prefer gnome/debian based systems to KDE based other distros?
Btw you can have KDE or Gnome on debian, as its just a matter of choice.
Gnome is much simpler and easily modified to ones need.
KDE has has more Windoish feel and at times it provide settings which one would never even bother to care about. But KDE 4 looks promising, hoping for a stable release. And I hate that K in every KDE application.
