Pew Research looks at generational difference in online activities.
Excerpt: Contrary to the image of Generation Y as the "Net Generation," internet users in their twenties do not dominate every aspect of online life. Generation X is the most likely group to bank, shop and look for health information online. Boomers are just as likely as Generation Y to make travel reservations online. And even Silent Generation internet users are competitive when it comes to email (although teens might point out that this is proof that email is for old people).
