Last week, Optoma finally released its PK102 pico projector in the United States and it's selling for about $265 - just $35 more than the PK101.
As a matter of fact, the PK102 and the PK101 have a lot in common. They have the same native resolution (480 x 320), the same traditional DLP engine, and a slightly higher contrast ratio - 2,000 : 1 (up from the PK101's 1,000 : 1).
But there are some improvements from Optoma's original pico projector, which was, according to Engadget, considered the "industry's poster child." The PK102 is slightly smaller and features 4GB of internal memory. It also has new connectivity options including composite video input and a universal port which is capable of receiving VGA and component video signals. It also has a built-in speaker and can play MP3 files.
