What I think about the way this is going is that increasingly people will be able to choose to experience their content wherever they like. Where they’ll choose will largely depend on the situation. In a household like mine, the television is a great choice for a lot of content because the couch is more comfortable, the television is larger, the sound is good (although my computer’s sound is possibly better when it’s “docked”), etc. In households with a lot more people than mine, or with children, or where people want a lot of privacy, etc., then they might go the other way, choosing a personal device rather than the television for those reasons.

Also, I don’t know how much longer these distinctions will exist anyway. I’ve almost never watched television shows on my computer. When I didn’t watch them on my TV via the PS3, I watched them handheld on my PSP. Is that lean-back or lean-forward? Sometimes when I want a nice large view and plan to spend a lot of time and want the comfy couch, or when I want to use a different sound system to demo audio in a more “home theater” setting rather than a more “studio” setting, I plug my laptop into the television and lean back with a keyboard on my lap and the mouse next to me. That’s sort of both, under your definitions, isn’t it? I mean, I’m leaning back, but I’m using my computer, but it’s on the TV.
