My parents thought that 1:1 Computing was an exciting way to interact fully with the subject Economics. However, my parents were concerned with distraction you might get from laptops just like any other parents.
I think that if you reach Junior year, I think that most of the students get responsible of their academics. So there will be less of distraction. If we only set our laptops fully optimized for studying economcs, there would be no worrys. For example, you can register the class blog, moodle, and other economcis websites to bookmark to prevent going to irrelevant websites. Also, I think that our teacher is having full control of what students are doing on their laptops.
In short, I think that the distraction you get from laptops are neglegible.
