I bought a cellphone sized e reader, called the moaan inkpalm. It being so small has really helped me get more reading in. There are better ones available now, but it's pretty cheap for what it is. I can pull it out whever i'm waiting for my family somewhere, and pick a book that i'm in the right mood/mental state for.

Sometimes a book just isn't for you, or you need something with more fun and less substance because of all the other demands on your time and attention. I used to plow through difficult books when I had the time. Now that I generally read in 15 minute stretches that's not nearly as easy. It's not a black and white thing.
