"I have previously argued that wubi installer is the best thing
since LiveCD, because of how stupendously easy it makes installing
Linux for first time users without the hassle of disk partitions
and risks of loosing data. But KDE on windows goes a step further
by installing a complete desktop environment on top of windows.
Don’t get me wrong, this is by no means "using linux", for
lack of better words think of it as an open source "windows skin"
(Desktop Environment) on top of proprietary MS Windows operating
system, but unlike traditional "Desktop Skins" it goes several
steps further by actually porting native KDE applications on
windows."
