For the last few months, I have been using a very handy gadget: a pico pocket projector from Aptech that has both a battery and stored memory. The device has a very bright LED with an array that can project, on any surface, either a series of pictures or anything that is on my laptop. I have downloaded several PowerPoint decks into its memory and then I have a visual backdrop that I can put up during any meeting or any chance-encounter. The image size depends on how much ambient light there is but, in most instances, a 24"-to-36" picture is typically adequately bright to work. I have projected on a floor, on the wall of a bar, on a tabletop, or even on an elevator wall. Once, just for fun I wore a white T-shirt, and projected my presentation onto my chest.
What is the business use for a pico projector? I truly believe that a picture is worth a thousand words and to have all your pictures available at a touch of a button is very handy.
Snapshots of your kids, you latest vacation, and your dogs are not as interesting to others as you may think, so don;t load them on your pico. But images that help tell the story of your business can be very cool. I recommend that you get a pico projector of your own, load it up with information, and carry it with you everywhere. You never know when you might meet the person who is in a position to help you do something amazing with your company.
