I actually miss the MS-DOS days. Microsoft still had a usable OS back then...
I still use the "DOS" option in WinXP every now and then. Like when I want to create 26 directories (A-Z) to store pictures, mp3s etc. "md a", "md b", "md c" is way faster compared to "rightmousebutton-new-folder-typeinyournewfoldername-enter".
Nothing faster to use than a command line OS :-)
