How would you change Google Glass (Explorer Edition)? (Lemme guess, maybe battery life?)

The two-hour battery life wasn’t ideal, and there were more than a few privacy concerns that, in hindsight, have been borne out. Personally, the most exciting feature for me was the navigation coupled with the bone-conducting headphone, and there’s nothing greater than having directions beamed directly into your cranium. Still. The question here is simple: if you had a meeting scheduled with Sergey Brin, what would you tell him to change for version two?
