New models hit the pocket size projectors or microprojectors market.

Since last year, a wave of microprojectors also known as pico projectors, have the market place. They are pocket size gadgets that can play a video on an iPhone or some handful other smartphones and transform almost any surface to a 60-inch screen.
The first one to hit the market was the Optoma Pico PK 101 by a company called Optoma USA.
One year after its introduction, the Optoma now retails at most places for $229 except at Best Buy who has it listed at $299.
After all the buzz garnered following its introduction, now there are two new entrants in this niche market.
One of them is the Cinemin Swivel by WowWee Technologies and the other is the 3MPro1020 by 3M.
Both these two new devices are a significant improvement from the Optoma Pico and they are both hitting the market this month and strikingly enough, they both retail for $350.
