Specifically made for the iPad, the ProPrompter HDi is a full size mobile teleprompter from Bodelin Technologies. The device connects to the base of pro and most consumer cameras and means you can use a shiny new iPad as your very own teleprompter.
Of course, iPads are sold separately. As is the ProPrompter App (available from the App Store for US$9.99).
The unit holds your iPad tightly in place, and works by reflecting the content from the iPad onto a mirror through which the camera also records the presenter.
The ProPrompter HDi also offers Remote Control Sync, which allows an off-camera operator to view the script on another Apple mobile device in sync with what the presenter is reading.
More information can be found at the ProPrompter website. The device will launch for a special price of US$850 (around $915).
