For road warriors, mobility is the name of the game. And nothing gives you more of it than the optional Smart Attachment Module (SAM). In fact, it may be one of the smartest investments you'll ever make. That's because it lets you store your presentation in flash memory so you can leave your laptop behind. Now you can go from your office to the airport and then to the conference room with your projector in one hand and your presentation stored on a flash memory card in your shirt pocket. Or you can pull up presentations from the network with the network capability or with wireless technology. That enables a member of your staff to finalize your presentation while you're on the plane. Upon arrival at your destination, just connect to the network using an IP address and download the presentation. The wireless capability allows you to walk into a room and connect to the projector with another wireless device. Like a digital camera, the HP Digital Projector mp3130 leverages digital technology, flash memory and the Internet for maximum convenience and efficiency.
