If anything, that should be a decision left up to the professors. For the college itself to ban laptop use would be a bad call on all fronts. What it boils down to is what utility a laptop provides for a specific class. If it's a literature class where most of the learning is done through presentations and textbooks, then using a laptop in that specific class wouldn't be that important. If, on the other hand, you're taking a physics course and you have supplemental programs that aid you in doing whatever you need to do, then laptop use is a must if there is no other means to proficiently complete coursework at school.
If a professor notices a lot of students are just browsing the internet and not doing class relevant work, then I think the professor should have the authority to restrict use.
