It's certainly bright enough in a darkened room, but it will never replace your larger projectors. But then again, how often would you hook up a mobile device like your iPhone to a large projector? This is a totally portable system which fits in the palm of your hand. Bigger news is on the horizon, as Microvision just unveiled its new projector module which is HD AND 50% more lumens. I don't know the life expectancy of the projector, but it's a really long time. Also, in response to your flight sim idea, have you seen my immersive gaming demo which was featured on Engadget a couple weeks ago (using ShowWX and iPhone 3GS)? In that Youtube video, I turn a room into a 360 degree environment using a game which incorporates the phone's compass and accelerometers. BTW, I'm having a ton of fun playing with this projector, but I am not an employee or partner with Microvision. I do own some common stock, though.
