Well, I hang a big rollup screen on the front wall of our multi-purpose living room, so that the screen will cover the built-in "entertainment shelves" and an unused fireplace when it is rolled down. The living room is an open space and has huge windows that do not even have a shade (yet). Still, the projector produces a stunning big picture after dark. I could not have possibly achieved this with a big-box TV or a plasma.

Projectors becoming this affordable lately, front projection is well worth serious considerations with or without a dedicated HT room.

Something to keep in mind for your future planning...
