Hi Rich,
There's actually some features in KDE I like that Windows doesn't have -- the option for the screen borders and window borders being "magnetic" is pretty cool for letting you easily line up a bunch of windows without gaps.
On the other hand, I still think setup.exe is generally better than "urpmi -v PackageName" and far superior to the GUI wrappers for RPMs that typically don't even give you the option to change installation directories... grrr...!
