What do you mostly use the internet for?
communicate with people (over msn to friends, over this forum to talk computers and stuff).
and for entertainment (download music, movies, etc.)
All of the above to some degree. Although 'Entertainment' covers such a wide range of activities, such as watching DVD's, listening to music etc... I just love playing games, especially online.
all the above plus shopping, looking for work and probably other stuff too
entertainment, communication, side business
In that order
