The most important thing I'm watching out for is social life. Will GenY become isolated behind their computers, with a social life consisting of online gaming and online forums? Or will GenY rebel against technology and start going outside their house?
I will agree that technology is causing people to stay inside more. When TV came along, children went outside when there was nothing good on. When video games came along, children went outside when they were bored of the games they have. Can one say "I'm bored, and there's nothing good on the internet"?
Sesame Street recently made a change to Cookie Monster. Instead of "C is for Cookie", he says "Cookies are a sometimes food". This was done to fight obesity in children.
Cookies and junk food aren't necessarily the cause of child obesity. I ate tons of that 5hit when I was young. I'd just go outside and burn off all my energy. I remained a skinny little 5hit. I'm guessing it's lack of exercise. Too much to do inside.
I also wouldn't agree that it's marketing. Check out

What I do notice, and I wrote a separate post about it, that industries have the power to tell people what's in and what's out. Dressing all women like Britney and Christina , including girls 10 years and younger is the "in thing" right now. Stores are filled with low rise jeans for all ages. Therefore, your 8 year old daughter's ass crack is going to stick out when she bends over. Might be nice for pedophiles, but socially, it's disgusting and quite embarassing for the child. And don't get me started on thongs for kids which do exist.
