In the past it was costly to setup a projector, having to buy not only the projector, but all of the accessories as well as having a computer and other digital devices that can interact with the projector. However, Nomad Technologies Inc. has set out to do the world a favor by putting together the new PS3000 display cart. This cart is an all in one portable answer to all of your projection needs. The cart carries not only a projector, but a digital camera, a PC with a preview screen so you can see what you presentation will look like through the projector, speakers, and a DVD/VCR player. What more could you ask for?
