LAS VEGAS — The Teleprompter is an essential tool for newscasters and public speakers.  A much less expensive device from Prompter People allows speakers to control the the flow of displayed text with their iPhone.

The display can be an iPhone, iPad, Mac, or notebook PC that is held in a cradle.  It's priced around $500.

Our West Cost producer Jeff Brooks caught up with Mark Ditmanson on the show floor for this demo.
