Due to its unique feature Optoma Pico PK-101 Pocket Projector can be considered as the coolest gadget of the year 2008.
This 4.1 inch gizmo is capable of projecting your favorite images or media files sharply on the wall or on any plane surface as close as 8 inches and as distant as 8 feet away, even in daylight. All you have to do is just plug it into your iPod or iPhone.
It weighs 4 ounces including the battery and is smaller and lighter than many cell phones. It is equipped with a rechargeable battery that lasts for 1.5 hours. According to some user reviews the sound output is somewhat dinky but it is not a problem when you are using it with headphones or Bluetooth Speakers. Moreover it not that expensive either.
