Here’s an interesting photo I received in an email [Thanks, Carl!], you can see a larger version here.
I find it interesting that not only everyone except for the person circled in this University of Missouri classroom has a laptop, but every laptop is a Mac. I can only imagine how hard it must be for a student to pay attention to a lecture when the World Wide Web is available to his or her fingertips.
Laptops aren’t often used in the college courses that I teach, but when I do see them open, the class size and room is small enough for me to walk around.
