I've always liked Optoma products - they are good quality products. But seriously? The specs look like it is just the Optoma PK301 in a much, much larger size and a higher price.
Why not get the AAXA M2 micro projector with the Iphone adapter cable? Not only do you get full Iphone connectivity, you also get:
*XGA Resolution
*2x brightness
*HDMI input
*Multimedia player
*Save some money! ($350 on amazon)
