I have the opposite problem. I hate GUI bullshittery. With the command-line I can string together multiple tools with options to work the way I need them to.

If you throw in a tool with nothing but a fancy GUI, I can't simply pipe data through it. I have to find buttons to click, search for hidden menus, resize windows, etc. What a waste of time! Give me a man page any day!

He says Excel is superior because it makes charts easier? Guy is in the wrong field. Learn some octave or matlab.
