The longer a press release is, the more the company has to hide. This is a Bluetooth-enabled trackball. You and I grasp this concept immediately—roll ball, make object on screen move. However, the makers of the Ball inform us that trackballs are popular with air traffic controllers and were once used to play Centipede. Obviously, the media relations staff is reaching here.
After an unprecedented two years of research, the Blue Ball is currently available for about $69. It has two buttons, a scroll wheel, and the ghastly pallor of a forgotten technology made wireless.
