I guess it depends on the kind of application. I use the keyboard a lot, but I'd kill myself if I had to use the git command-line interface. Once I bought Sublime Merge, I stopped learning what was (and still is) a waste of time to me. I'm faster with a global visual description and a mouse for some tools.

While Sublime Merge is a nice piece of software, Magit is the very best example of a power user tool. Fast, versatile, and intuitive.
