While the Internet has held my hand through my adult life, my childhood was devoid of doodads (unless you count the portable Pac-Man console my brother and I used to fight over).
Plyming didn't state it specificially, but if you take this view to its logical conclusion, a regular 42-inch HDTV would get pushed into a no man's land somewhere inbetween -- it's not portable, not immersive, and therefore not able to compete in the long-term.
