Anyone seen or tried these new laser pico projectors?

Are they worth the $500-600 people are charging for them?

Found a picture of someone using it online:

I think another company Microvision also has one. I'm really curious about them but no one seems to have them... Been asking on a couple of forums already, I want to get some real feedback from normal guys :)

My friend who works for a large IT company says they are awful and only sell as a gimick. They have said avoid them at all costs. They have limited power which means they are only good in very dark rooms (not my opinion as I have never seen one, jut what I have heard). Your better of buying a small portable projector.
