Users can feel free to leave their laptop behind when going to deliver a presentation, with the itroduction of Research In Motion's BlackBerry Presenter accessory.

Presenter is a conveniently small and light device that easily plugs into a projector or monitor, then lets the user display a Microsoft PowerPoint presentation wirelessly from their BlackBerry smartphone.
“Mobile professionals are always looking to carry less when travelling,” says Glenn Laxdal, vice-president: product management at Research In Motion. “BlackBerry Presenter equips mobile professionals with a simple, secure and convenient way to deliver presentations directly from their BlackBerry smartphone, giving them the freedom to leave their laptops behind.”
BlackBerry Presenter gives users easy control of their presentations, allowing them to navigate their presentations, view speaker notes, loop presentation slides and even reference information on one slide while displaying another. Thanks to a wireless (Bluetooth) connection between the BlackBerry smartphone and BlackBerry Presenter, users can also walk around freely while presenting (supports roaming up to 30 feet between the devices).
