[U]sers moving between KDE and Windows 7 won't find many differences in basic navigation. However, the differences in how features are implemented are obvious as soon as you start configuring.They certainly are. Every application in KDE seems to have one hundred configuration options, as does every panel, widget or window. It's clearly aimed at "power users". Fiddling with configuration options is not my cup of tea. I like the minimalism of Gnome, and Gnome applications.
Give me Gnome 3 with its almost complete lack of configuration options any day.
