Optoma has began shipping its PK-102 pico projector, its successor to the existing PK-101. Like the PK-101, the PK-102 uses DLP technology and has the same 480x320 resolution and ability to project images up to 60 inches in size. Unlike the PK-101, however, it now has 4GB of built-in storage space and the capability to play back MP3 files from its built-in speaker. At the same time, the PK-102 doubles the contrast ratios of the PK-101 to 2,000:1.
