I had a laptop in law school. In the classes I was engaged and challenged in, I paid attention. In the classes where a professor lectured about minutia that would never come up anywhere in the world again, I zoned out and facebooked or IMed. It had nothing to do with the computer, it was about the materials being taught and the way they were presented.
Fortunately, it ties in with the previous post and how important it is for a professor to engage students in the classroom.
