The screwdriver is maybe the last thing in the world that needs a reboot, but the new Black & Decker Max Gyro is the kind of non-essential evolution we can get behind.
The little 4-volt handheld tool mimics improves upon the function of ye olde analogue screwdriver with a built-in gyroscope that anticipates your movements. Turn your hand clockwise and the bit drives, turn your hand counter-clockwise and the bit goes in reverse.
Superfluous? Maybe, but it should take the strain off your trigger finger if you've got a long job to do. The Black & Decker Max Gyro will be available in November for $US40. [Black & Decker via Engadget]
