Recently a new line of very small data projectors has hit the market. These pocket size devices provide mobile projection for laptops and portable devices such as digital cameras, mobile phones and iPods. One that was recently written up in the New York Times is the Optoma Pico Pocket Projector. This device is about the size of an iPod and can produce an image up to 60 inches measured diagonally. It is powered by a battery that provide up to 90 minutes of continuous use and can easily be recharged or powered using a USB cable connected to your laptop. The size and portability make this an interesting device for small group work. Students could use this type of device to project their work onto just about any flat surface. The bulb is not replaceable, but is rated at 20,000 hours. The review by David Pogue of the New York Times is quite positive and I have recently ordered one and will post a more detailed review once I have had an opportunity to work with it.
