The touchscreen is internally powered via USB. Troll Touch says that its custom touchscreen overlay design and innovative component integration technique does not alter the machines form factor in any way. To the casual observer, the system does not appear to have been modified. The 24-inch display joins the Apple 20- and 30-inch Cinema display touchscreen systems the company currently offers.
Customers may purchase the touch-enabled display from Troll Touch, an Apple VAR and PSP, for $2299 or they may supply their own previously purchased machines to the Valencia, CA company for custom touchscreen integration. The cost of integration is $1399.00 and includes the integration, a custom engineered touch sensitive overlay, touchscreen controller, cables and complete system test.
