I still do the majority of my work on Linux in terminal windows. It loooks like you're referring to the GNU/Linux operating system, rather than the Linux kernel; if so, would you please write "GNU/Linux"? The GNU Project needs to get credit for the developing the GNU system, since this helps us do more of everything we try to do (including the Gimp). So it is a GNU convention that we should call the system GNU/Linux, the combination of GNU and Linux. That gives us a share of the credit, while still giving Linus Torvalds a share as well. See http://www.gnu.org/gnu/linux-and-gnu.html for more explanation.
