Some personal experiences:

• huge fan of audiobooks, there are lots of good ones, and you can pretty much search for them like regular books - very good % have audio versions at this point (thank the ipod). check Audible.com. Obviously books that have significant math or charts are a non-starter, but many good psych/business/biographies/history and popular science are available, not to mention fiction.

• try changing speed settings. my setup is audible app on the iphone, it supports cloud storage (convenient) and has up to 3x speedup. I listen to non-fiction at 3x easily at this point (and can probably do 4x if they make it available), and fiction at 1.5 (1x feels slow at this point, so it seems I overclocked my brain a bit!)

Audiobooks are great for commute and other situations that require your bodily presence but not your brain (shopping, etc). They reduce my annoyance/stress level dealing with these things.
