If they’re yet showing up on your radar, they soon will be.  Portaprojectors (aka pico-projectors, pocket projectors) are pocket-sized video projectors that can be hooked up to a camera, a laptop, or yes, even a cell phone.  Imagine their uses: travelling business presentations, portable movie theaters, video games in bed, etc.  Some upcoming cell phones should even be released soon with micro-projectors built in.  Who said 2010 wasn’t the future?
