iPin is the final brick of transforming your iPhone into a professional laser presenter. It is delicately engineered to be small, and so small that it fits just right inside the headphone minijack. With downloadable iPin app support, it allows you to control presentation slides straight from your phone. No more fumbling for new batteries or misplaced laser pointer. iPin is ready to use anytime, anywhere. iPin – makes your phone shines brighter than ever! I will be keeping an eye on this one to make sure it compatible with the newer phones.
