Ubuntu is really a charming distribution of GUN/Linux . I've noticed it two months ago. The live CD instaills very easily and the "face" is beautiful . it is interesting that the X of Linux abroad is mostly Gnome while the domestic is KDE .well ,KDE looks more flamboyance for its class-style look . Gnome is simplicity comparatively. Why ? May be the people who use Linux aborad miss their Unix ,Hehe . Unix looks simplicity as well .
?Kubuntu is based on KDE ,it is the extending project of the Ubuntu ,seems less important than Dubuntu . But? frankly speaking ,Kubuntu looks more lovely
