I love staring out plane windows. On a flight over interesting areas, I can spend a lot of time watching the ground scroll past. I love watching sunrises and sunsets, and observing different cloud patterns. Anything that reduced that experience would be bad, if you ask me. Plus, as has already been mentioned, they are an important security measure for passenger flights, especially in emergency situations. That's why they ask you to lift the blinds for takeoff/landing. Fire crews are able to see inside the plane and look for smoke/flames/trapped people.
