As you can see, the reason they want to keep this under wraps for the time being is that the quality and brightness are certainly not ready for prime time yet; while the unit we saw used lasers as the light source, we're told that an LED-based model still in the lab offers significant improvements.

Engadget tested the new cellphone projector from Texas Instruments. The technology already works but still needs some improvements to beef up the brightness and quality. So far I think it looks pretty promising, the phone they used for the prototype is still quite big but I think that will change as the technology matures.
