This isn't a needed at all but I just really love the idea of being able to program some litle flying robot to follow you around. Helping you carry stuff, remind you of apointments, and write down importent conversations. Maybe even that you could leave it to another player when you go offline and they would to get a clear status rapport of on going prodjects.
Sure, the same info could be on a monitor on a drone or in a ship/base. I just like the idea of a little every day assistent x)
