The time spent gaming statistic, if you thinking about it, isn't a measure of which platform has the most "r33l gamerz" (is "r33l" a thing? if not, we're starting it) but what people are buying the consoles for. A look at time spent watching DVDs and Blu-ray's (27 percent on PS3 vs 11 on 360) reminds us that there are probably plenty of non-gamers that just bought the box as a cheap Blu-ray player padding the numbers.
So, the consoles all do different things and different people love them for different reasons. It's a veritable rainbow of useful applications and applicators. It's ... crap, you're already commenting, aren't you?
