The Optoma PK320 is a digital pico projector around a hand in size.
It's throws out 100 lumens and has a DLP (led) lamp, ensuring a long lamplife (est 20,000 hours).
Released in early 2012, the pico projector may very well have been a market leader, but at the time of writing the price for the pico at $380USD is a little high, compared to what you can get for spending around $100 more.
