Query: Poor battery: approx 5.5 hours

I don't usually write reviews but I was so badly treated (or rather: ignored) by Apple's service that I felt I should warn others. Beware of the battery rating. "8 hours" means one song played over and over. Under ordinary circumstances you will average about 5.5 hours. And, heaven forbid, you should skip to the next song, you can drive the battery down to 4 hours or less.On the positive side: the wheel interface is very good.
