About the Delta II Keyboard matrix:

Skydiving equipment designers consider the user's muscle memory reflexes to make their products consistent and quick to learn & operate.

Chicago Logic uses the same muscle memory consideration to create a superior mobile keyboard having big, easy to read, accurate to press buttons - arranged in an ingenious layout that is learned almost instantly.

The patented Delta II tm modified QWERTY keyboard layout appeals to your muscle memory reflexes. Every letter is in proximity to where you already look and reach for it on your PC (QWERTY) keyboard.

The result? Your muscle memory reflexes cause you to learn and type on the new keyboard extremely fast.
