CS student Carolyn blogs that a debate has sprung up on her campus about whether it is acceptable to use a laptop in class. And her school is hardly alone when it comes to struggling with appropriate in-classroom laptop use (vendor/corporate trainers would no doubt commiserate). The problem, she says, is that the OCD Facebookers aren't just devaluing their own education — there's a certain distraction factor to worry about. 'Students,' she suggests, 'should also communicate with each other more and tell their classmates when their computer use bothers them. I'll admit it, when I'm trying to pay attention to the lecture, even someone's screensaver in the row ahead of me can be a major distraction.' Try using an iPhone in a movie theater to get a taste of the quit-being-an-a**hole candor that's typically missing in the classroom.
