On the spatial literacy site you can find a classification of "neighbourhoods using data about our levels of awareness of different information communication technologies, how we use them, and how we think they might improve our quality of life." (in Great Britain).
The 8 main categories are:
3. Becoming engaged
4. E-for entertainment and shopping
6. Instrumental E-users
7. E-business users
It's not really linked to age-differences, though from the group of e-professionals it is said these are mostly young people. It demonstrates the wide range of comfort levels and uses of technology. Again, it's not really linked to type of access, yet I remember seeing a graph indicating how internet use changes with the change from dial-up to broadband. (and ofcourse this is different from use from cybercafes or other joint facilitaties).
