To use your comparison to the iPad I think current 3D technologies/implementations are comparable to the clunky oversized Windows tablets that failed. They had the right form factor but were missing some important bits (software, battery life, price) to make them really compelling. Someone will come up with a great enhancement to film in the future that leap frogs today's gimmicky 3D effects and it will be very successful. I think maybe VR glasses could make a comeback now that we have very tiny high resolution displays and advanced types of motion tracking. I don't think we're that far away from an amateurish holodeck sort of experience. A gyro tracks your head movements and a camera tracks your body movements. The VR glasses wrap around your entire field of vision with highly detailed multi-channel headphones. It would be very immersive. You couldn't reach out and touch something of course but you might get a really strong sense of being in a 3D space.
