What would be very cool and also actually useful, would be to replace the glowing logo with an OLED panel. Those things are so thin (flexible) that it seems like you could layer one in with virtually no increase in thickness, and since the display can retain its contents without power, it wouldn't use much battery.
Then you could use it to display things like battery level, alerts, etc., or more essential stuff like a picture of your dog. 🙂
