Recently, Google launched their latest product, Google Glass. No doubts, that is a very creative product. No screens at all, the glasses will become your display, and no keyboards at all, it uses voice commands. Moreover, it has a camera in the glasses. So, you can use it to capture what you see into Youtube or translate the words you just saw into a different language. That is very sci-fi and too advance. I think the general public is not easy to get used to this kind of operating computer. Moreover, the price of Google Glass is an serial consideration, whether that is too expensive.
