Surprised, isn't this something that everyone does on OSX right after install / opening a new computer anyway? I don't understand how they came up with the slow-as-molasses defaults.<p>Mouse responsiveness has also always been inexcusably sub-par compared to Windows and Linux.
This is a <i>preference</i>, not an <i>optimization</i>.<p>I have very high key repeat and mouse speed on my laptop, and when coworkers pair with me they don't say, "Wow, your vim is so much faster than mine!" They say, "Geez, your computer is crazy!"
