Casio has unveiled their ultra-slim XJ-S30 DLP projector. This projector (pictured on top, for size comparison) measures in at 1.25 inches. The other standout features include the option to receive data via Wi-Fi or directly from USB. It has a 2,000 lumens brightness rating and a measly resolution of 1024x768, which would be good for Powerpoint or showing that slideshow to grandma, but not so much for video or gaming.
