I listen to audio books any time I get a chance. On the way to work, walking, in the car and so on. One of my fav. things about the iPhone is how it handles calls and txts while listening to books with headphones. Phone rings, book mutes, click headphone button to answer call, talk into mic, click to hang up and book resumes. Love it. After clicking it also seems to back up about thirty seconds to give you a chance to remember where you were.
I changed to Phillips in ear buds after two sets of Apple ones died though. About the same price and work really well plus last so far twice as long. :P
I AM having that issue that Zolly brought up about the annoying and unnecessary "data is turned off" warning when I am texting though. Didn't notice it so much before, Zolly but now that my Hubby has been away a few days and I've been texting more it's become very obvious! Why on earth are they bothering to tell me that during a text which goes just fine with 2G? I wish there was some place to turn the warning off.
Anyway, back to audio books, they also fixed (some time ago) the problem with when syncing losing your place. I actually can't think of any way they could improve audio book function. It's perfect. You guys know about the fine scrubbing ability? Hold your finger down on the scrubber, drag your finger down the screen and you get medium, then fine scrubbing. Very cool.
