Pocket projectors arent a new concept, we saw the 3M MPro110 not so long ago along with the Dell concept pocket projector and the Texas Instruments DLP Pico-Projector which adds projection capability to mobile handsets even. Now a company called Aiptek has managed to make pocket projection go cool. The portable, palm-sized device can project up to a 50-inch image on walls from between 21cm and 180cm away. With a 640 x 480 resolution in 4:3 aspect ratio, it can playback JPEG, MP4 and MP3 files and has a built-in 0.5 Watt speaker. It has 1GB internal memory, can read data from an SD card slot or can connect to other gadgets and sources via AV in. Powered by a rechargeable lithium battery, the Pocket Cinema uses a "high powered" 10 Lumens LED to project the imagery and offers around an hour's worth of battery life.

Weighing in at 100 grams and measuring 12.5 x 5.5 x 2.3cm, this funky little gadget is priced at around $510, which is a steal for those long over stays in hotels.
