I'm sure you know this, but...
If you are talking about the advantages of projectors, you need to talk about the shape of the screen as well. If readers are just getting into home theater, and need to buy a screen and projector, they need to know this.
The advantages of projectors are size AND shape. When a widescreen movie comes on - almost all modern movies - you need to make the image bigger, not smaller. Projectors have zoom lenses, hopefully motorized and with several memory settings. The experience of pressing a button on the remote and having the image zoom out to 2.39:1 in front of your eyes is amazing every time. To have this, you get a 2.39 screen, not a normal 16 x 9 that they will try to sell you without batting an eye. Then there are ways of calculating the projector distance that you need to be aware of.
And note, 110 inches is NOT a big screen. My painted white wall screen is 5 1/2 ft high and 17 ft wide for Cinemascope and Cinerama. My projector is an inexpensive ($1800) Epson, and is VERY bright at any screen size. I have half a dozen zoom settings in that can accomodate anything the streamers throw at me.
