All true, but worth a brief addition: these viewing distance / screen size / resolution models all assume average adult vision, so if you are one of the folks both lucky and unlucky enough to have above-average vision (or below, for that matter) you should take that into account. As but one example, the parent's example transition at 7 to 8 feet would occur around 10 feet for me. Above-average vision is great on paper but translates into more expensive displays positioned farther away. :(
