I like projectors... I just don't like how you need a dark room for it to be effective, the limitations to brightness, colour, resolution etc, the energy drain, or the slow refresh rates/"ghosting" (for fast-paced videos like sports/tennis or video games).

And the fact that for good quality ones (to compete properly with TVs) its gets very pricey.

And that when all your standards are met, the projector usually lights up your room by the excess light bouncing off the walls... much more than a TV's glow lighting up a room.

Dunno, it just seems like a good idea... but more compromises made on quality.
They should make a curved blank screen/blinds and a projector that can light it up circular around a user/users.
