I read ebooks and listen to audiobooks. My kindle syncs with the kindle app on my phone for ebooks. So anytime I'm waiting in line for something, like at a grocery store I take out my phone and start reading my current ebook (or more often hacker news). Sometimes I'll take my kindle with me on a walk and stop in the middle to read for a few hours if it's a weekend or something. If it's during the week I don't normally read from the kindle directly more than an hour a day. If there is a tv show I'm watching sometimes I'll do that instead of reading.

For audiobooks I listen at faster speed so it's like reading more content than the time actually consumed. If I don't feel like listening to a podcast I'll listen in the car. I'll also listen while I'm doing dishes or that sort of thing around the house. Occasionally I'll listen to an audiobook while playing videogames.
