Unfortunately, unless you have a subscription to the Puget Sound Business Journal, you can only access the introduction to this article from the link below. The whole article might not say that much, who knows, but what intrigues me is the accompanying photo which, I assume, is also only visible to those with a subscription. The caption to the photo is "Mobile devices offer business opportunities for Washington companies such as Microvision, which makes this image projector for iPhones." A bit presumptuous, probably, but hey...
