I really like the command line interface (CLI) in Linux. It bestows great power upon its users, and I spend a good deal of time availing myself of those powers. And yet without the GUI desktop I would still be limited. It is through the combination of the GUI and the command line that I find the power of Linux to be more fully realized
As with many things in Linux, there are several choices available for desktops. A short list includes Xfce, MATE, Cinnamon, LXDE, GNOME, KDE, and for the kids, Sugar. I have tried all of these at various times over the years, and I always install all of them on my main workstation so that I can try out the latest versions of each. But despite the fact that all of these desktops have many good features, I always return to KDE.
