I want an IMAX viewing experience with booming surround effects and I only have time to watch when the kids are all in bed. Compared with a house large enough to have a dedicated sound-proof theatre room, $3500 doesn’t sound too expensive.

Also not everyone lives in a house, I’m sure Manhattan condo owners can afford the price of the theatre gear, but cannot afford the space required for them to be used optimally. Wealthy people don’t all live in mansions.
