As someone with a severe visual impairment, I use the command line as much as possible. It's easier to see and there is less I need to see. If I can type a command instead of having to hunt for a button, it means I can work that much faster and anything I'm looking at will be text, uncluttered, and high contrast. From the command line, I can navigate the filesystem, install software, search, edit text, download files, play music, and send email all without even looking at the monitor. Once you're comfortable with it, you can just close your eyes and let your brain and your fingers do all of the work.
