Das Keyboard is an enhanced 104-key USB PC keyboard equiped with 100% blank keys mounted on precision and individually weighted key switches.
Since there is no key to look at when typing, your brain will quickly adapt and memorize the key positions and you will find yourself typing a lot faster with more accuracy in no time. It is amazing how slow typers almost double their speed and quick typers become blazing fast!
Ha! Anyways, that reminded me of the worn out keyboards attached to the computers in the UNIX lab we had in college.
