I remember seeing this on tv, the girls mother was outraged - but any hurt the young girl suffered was down to the fact that her mother allowed her on the machine, having not read the small print .
I had a go on my neighbours, it screamed, it whined, it shouted 'will you get OFF me you giant swampdonkey' (well, not QUITE in those words ' but it didn't upset me because I'm old enough , big enough (well, obviously) and confident enough not to let a machine upset me .
Honestly, its like people that get beat up over internet insults - its someone you're never going to care about saying something mean hiding behind something else. In the case of the wiifit, it's not even that intelligent.
I'm sure, if my next doors Wii knew me better it would say ' Hey, you;ve got a big ***** chunky thighs,and you good do with a haircut, but you have GREAT tits and I LOVE the piercings!' And hey, if I don't like what it says, I can always take a hammer to it ^^
