I'm nearly the same! I've found that I can't stick to a single book at one time--when I'm jogging, I don't want to think about technical things, I want to think of big picture ideas.

When I'm driving a distance, I want to get into the nitty gritty of something technical or informative with an audiobook.

When I'm relaxing, I want something interesting but not directly related to any of my work--I don't want to get my mind running on tasks I "should be doing"

Very much the same with browsing the "eye candy" type forums, Twitter, HN, Reddit. If I've got a good book, it seems to permeate my life for the duration of reading.
