I find the authors claims odd. Yes, people who used computers for work before everyone had a smart phone and tablets were plentiful still use computers at work. That hasn't changed. But what people use at home for things that are not work has most definitely changed. I know people in their 20s and early 30s who do not have a computer with a keyboard - and if they do, I've never seen them use it at home. In 2008, I would expect most people in their 20s and early 30s to have a laptop at home, that they used for basic internet stuff. I don't expect that anymore. The author seems to think only about professional activities. But from what I have seen, home consumption and day-to-day activities have moved off of "computers" and on to devices like smart phones and tablets. This is true for me personally: I have a work laptop, but I don't have a functioning one at home anymore. At home, I only use my tablet and smart phone. Years ago, my personal laptop broke, and I realized there was no point in replacing it.
