Paper dictionary

There are 18 students in my class. Their nationality consists of Chinese, Thailand, Silia, Saudiarabia, Russian, and Japanese.

They do not bring paper dictionary in class except for me.
Electric dictionary is commonly used by them.
Although it seems that using electric dictionary is quite usual for them, but it is usual for me to bring a heavy paper dictionary in my school.
The difference between them and me is attributed to the gap of our age, in other word the generation gap.
I get used to looking up a paper-dictionary. But recently young student are apt to use not it but electric one because electric dictionary is easy to use and moreover quite light.
Even though electric dictionary is good mobility, I am crazy about old paper-dictionary because it is easy to look up a lot of words at once.
