That's a really tough question. The only true advantage of a projector is screen size. There are other things like reflected light is more natural then the harsh light coming from a direct view display but this is controversial and in the eyes of the beholder. It really come down to light control. IF YOU DON'T WANT TO WATCH IN THE DARK/SEMI DARK GET A TV. A UST projector with an ALR screen is kind of a median device between conventional longer throw front projection and a TV. They can be more tolerant with ambient light to some extent but their draw backs are more expensive then conventional projection and still have the same flaws with even less options.
