Actually, people who are very deep into the "get off my lawn" phase of their life, that is old people, are generally not the greatest typists. For them, the ability to talk instead of type, everywhere and not just in google search (which already has this) seems like a huge help.

I'll never use it. It's completely useless to me. But if my grandma actually did anything else than Facebook on her computer I'd show this to her.
