Comment on "Are tablets the future in class?" (China Daily, Nov 1)

Most children in the United Kingdom have access to computers installed in their classrooms. Since the computers are strictly for education purposes, they do not contain any games.

Almost all students in my university in China have cellphones and not all of them can be monitored to see whether they are playing games or watching movies instead of using them to access study materials or information.
