Projectors are a small market with I suspect most sales go to corporate use. When I show my setup to people they are absolutely amazed, but very few are willing to dedicate a room to a projector. Using a projector in anything other then a dedicated room is a big compromise in PQ with every aspect except screen size. Of course screen size can be a very big factor so that's why people put projectors in less then ideal rooms and are very happy with them, but they are defiantly not the norm as most use a TV.
