Hard to tell how noisy it is with the video since you can't tell where the camera is in relation to the projector.
But, I don't like that we aren't told the screen size and the only video presented was an 'internal' test.
Would love to see something a lot more full featured that discusses the projector after it has been in use for a few weeks and you really know what it is capable of. Put it up on a real screen, or a white wall, and talk it up. See how large you can go, or how small, how it works with an iPod, or with .mp4 videos, or other stuff along with HDTV and PCs.
Just missing a lot, but what IS presented was good to see and is appreciated.
