Troll Touch today announced that it is now taking orders for its for Apple's 20- and 23-inch Cinema Displays. "Touchscreen systems eschew input from mice or trackpads in favor of direct contact with the computer screen itself." Troll Touch's touchscreens use PSR-1, Pressure Sensitive Resistive technology. The company said the units will work with any non-sharp pointer -- a fingertip, for example, eraser or gloved hand.
