I've spotted a curious difference between people in Hong Kong and people in Chicago: a lot less people in Chicago have hand held video game consoles.
That may be just because I'm in a university environment, and people don't have time for games (*snicker*). Since a lot of people have Xboxes or PlayStations in their rooms, however, it's not that they don't like games, but somehow consoles like the PSP or Nintendo DS is just not as popular.
In Hong Kong, I would see people playing games on one of those everywhere, while traveling or even just walking down the street. From what I can see of people on the El though, no one has one of these things. I really doubt I've even seen a single handheld game (except maybe really old Game Boys.
I wonder if it's a poverty thing, a stress thing, or simply a cultural trend.
