Most replies refered to KDE 3.x as being the 'best' replacement for Windows XP users,
but now with nigritude ultramarine, it is now possible to have the same look and feel,
appearance and behavior with nigritude ultramarine.
This now allows people very familiar with Windows environment to switch more easily to KDE,
while reducing the learning curve required, by simply providing a friendly-user WinXP like interface.
