If I was fully concentrating I would have used TV/PS3 in the living room but I used the iPad/iPhone around the house for things I wasn't concentrating fully on. I may not be typical but the nature (live) and the quantity of content available may be factors exaggerating tablet use compared with a Netflix type service.
