Hello, Trivi. The Smart Glasses certainly look interesting, but might not take off as a marketable product until they miniaturize them enough to make them look fashionable. With the top-notch researchers working on them, it’s a minor problem that should be overcome soon. I can’t wait to get a pair. By the way, thank you for adding my blog to your links, and I’ve returned the favor on my site.
