This is a huge hit on the market of projectors. Toshiba is the first company to launch a micro projector. This one is literally the size of a pen as illustrated. They will no longer use the traditional backlight but the new LED (Light Emitting Diodes) which has a life span of more than 10.000 hours.
This small projector will be perfect for many business and teachers that require which will give them a high degree of mobility. It will be available from February this year and it is expected to be sold at about $800 USD. Quite amazing for a new micro toy !!
