This is one of those "I'm an old man" type deals. I often have students who bring laptops to class to take notes or look at facebook with. It's caused me to reflect on how much things have changed since I was in college. Although most everybody had computers back then, nobody brought them to class. I had one friend who wrote his master's thesis on an old Mac Classic that for some reason couldn't save a word document unless it was less than 11 pages. So he had to stitch eight or nine ten-page documents together to make the entire thesis, and if he made changes to the first one, he had to go through and repaginate the rest of them manually. And I had another friend, in the dorms, who had one of these things--a Brother word processor. It had a 2-inch-tall green CRT screen, would allow you to save your document in an electronic file, and then literally type it out for you. It was really, really loud.
Things are a lot better now.
