I don’t think there is such a big divide anymore. The 40-somethings are as devoted to technology as their children are. They play games, use computers for work and fun, have iPods and iPhones and buy all the new stuff as it comes out. Also this generation of parents keeps up with pop culture almost as much as  their children do. Add that teenagers and their parents all seem to dress alike. In my generation, kids wanted to dress like their parents (the last generation to aspire to such); now the parents tend to dress more like the kids.
