Usually if you're working with a teleprompter(aka 'autocue', a device that that allows you to read text while looking straight into the camera), you're not going anywhere. I worked with one a few months ago and found it completely impractical. These things are so big and heavy that you need super heavy-duty tripods, leveling is a b*tch and you're basically stuck to one location. But now this company came up with the idea to use iPhones and iPads as a basis for teleprompters! This is absolutely brilliant: a portable package for spitting out long slabs of text wherever you want.
