I've shown them the iPad/YouTube combo and I always use it when I'm there. My dad uses BBC iPlayer for Formula 1 as well, so they're not averse to using the iPad+AirPlay. But they still gravitate to the Sony for YouTube. I'll ask them why next time I visit. I think one reason may be because it autoplays the next video in the search results, so they can search for, "Border Police" and just watch a million episodes in a row. Maybe they just have an inhuman tolerance for T9 input.
