"At least the Wii gets them up and moving, gets them interested. You never know, a kid who's good at Wii tennis might just develop a passion for the real thing."

Errrm, the last time I saw someone play Wii Tennis, the most movement they did was akin to a five kunckle shuffle (if you get my drift)...Can't somehow see this ever leading to some heffer strutting their stuff across a tennis court, huffing and puffing all the while... Obesity in kids has it's roots in poor diet and generally being apathetic to anything like getting off their arses and doing REAL exercise! Forget the Wii, kick their wobbly arses around a field instead...
