Troll Touch has begun shipping its TouchStar2 touch screen system for Apple’s new iMac. Both the protective screen overlay and USB touchscreen controller are internally integrated into the iMac so as not to detract from the unit’s appearance. The TouchStar2 sells for US$699; customers can either purchase it along with an iMac from Troll Touch, or they can send their unit in to be outfitted with the device. Turn around time is about 10 business days.
