I've programmed for a long time, since before the days of personal computers and graphical terminals (unless you count oscilloscope like vector graphics output devices). So, I'm quite comfortable at the command line and use it all the time. I think it's interesting that there are nevertheless a few tools that I find indispensable which don't run in a terminal: obviously, the "big" graphical apps (like those from Adobe) and web browsers, but even my apple track pad for scrolling works so well that there is nothing quite like it.
