Update=fail I have been in love with audible. The convenience of being able to enjoy a book and still get things done is priceless to busy moms. The added bonus of a free book of my CHOICE every month=awesome. Buutt the upgrade??? Now I have to use a credit to buy a book?? Why? I should be able to use or not use my credit when and how I see fit. Not happy about this change at all. Usually upgrades are to make the consumers experience better, more enjoyable. You missed the mark on this one.
