Technology in the Classroom?

Personal Response Systems (PRS), annotation devices, PowerPoint and Flash presentations, laptops, and smart phones. The list goes on and on. I am curious to hear the students point of view on the use of technology in the classroom, both for use by students and by instructors. Is it more of a distraction or would you consider it a legitimate teaching or learning aid?
