Eyewear or glasses with tiny displays that replicate a big HD TV experience promises to solve the small screen problem with handsets. Could this actually be the answer to the most vexing problem in consumer electronics? Kopin Corp., which makes the tiny dense display for eyeware, thinks so. I must admit. It's been a while since I was as taken with a technology concept. I have not tried eyewear yet, but The Sharper Image is selling a Kopin-based model from Icuiti. If it works as well as Kopin CEO John Fan claims, it could be a big winner. At $500, eyewear isn't cheap yet, but in volume, it could be.
