This will make a lot of people severely airsick. I'm a pilot with an iron stomach, but one sure-fire way to make me queasy is to hide visual cues from the natural horizon during maneuvering (i.e. during takeoff and landing). You don't have to have a window seat to benefit from real windows -- even a very slight peripheral view of nearby windows, or a view of shadows cast on the inside of the cabin are enough to make you feel better.
