There are plenty of iPad docks out there, but only a few are unique. Here’s one of them. The Wowwee’s Cinemin Slice is an iPad dock alright, but it also features a built-in DLP Picoprojector. The projection image isn’t too high in resolution though. At 854×480 resolution and 16 ANSI lumens (brightness), this device will not replace your primary projector any time soon.
However, it should work fine for a low-lit room and may quite well qualify as a portable home theater.
Cinemin Slice is a portable pico projector that lovingly cradles and connects to your favorite multimedia devices, splashing your movies, videos, photos, games, and slides on to walls and ceilings, and caressing these enlarged images with rich stereo sound.
