Laser manufacturer Novalux is working towards creating colored lasers that could be used in tiny, laser-based projectors for handheld devices like cell phones, MP3 players, and PDAs. These laser-based projectors could produce bright and clear images the size of laptop screens in well-lit areas and projections of up to 10 feet in darkness. The projectors also won't require focusing because of the laser technology. If this technology takes off, people could watch movies projected onto the backs of airplane seats, subway walls, and even fast food restaurant tables. I'm excited that this technology has the potential to revolutionize handheld gadgets, I just don't think it's a good idea to project your business all over the place. If the person next to me on a plane can easily see that I'm watching just a 30 second looped sequence of David Hasselhoff running on the beach, he's probably not going to tell me when the dinner cart comes by.
