I've been wearing glasses since I was eight years old; that's 22 years of a piece of glass that only allowed me to see a surface more clearly. Am I excited for something better...YES. Does it look dorky? When you have questions like what's the temperature and look at me weirdly, I'll let you pull out your phone and look it up yourself smiling back knowingly. If you're interested in the technology, it's truly wearable augmented reality coming soon! If you think of the practical solutions, think of a nurse or doctor approaching a patient; the chart right there available with a blink of an eye complete with history and diagnosis. Prices or movie times without going into the theater. It's uses are infinite. I might not wait for Apple to come up with something better.
