That's not the only mobile use case, though. My favorite times to watch MOOC lectures is when I'm on exercising on my stationary bike, for instance; it's either that or finding something on Netflix or YouTube to watch, but with absolutely nothing else to occupy my brain, it's a great time to watch lectures. My tablet is indispensable for this, but some platforms work better than others at providing a seamless experience.
Also, the final paragraph in the article makes a good counterpoint to this:
> Michael S. Roth, the president of Wesleyan University, is teaching a course in European intellectual history on Coursera. "People have to get over the idea of signing up for a course and not finishing it," he said. "We all have to get over feeling guilty. There is no right way or wrong way to use an online class. This is a great platform for lifelong learning."
