In his book "On Writing" (which is excellent, and also narrated by the author in the audiobook version — highly recommended) Stephen King mentions that he reads ~60 books a year and that he fits his reading into any 10-minute chunks he can find throughout his day. Waiting room, bus stop, ball game — it's all enough to get a bit of reading done. After hearing that, I decided to load up my phone with audiobooks and put them on whenever I'm walking anywhere, even if my destination is just a few blocks away. Works amazingly well, and now I'm reading a ton more than I ever have in the last decade.
Even better, I think text-to-speech is basically good enough at this point to read books without an audio version! (I've found that I need to concentrate a lot harder when I'm listening to a OSX text-to-speech recording, but maybe there are better services.)
Can't do it when I'm programming, though.
