Why is this so badly designed for audiobooks?

Thank you so much for your review.  It will prevent this couple from buying the Jam, at least until some of these issues are resolved.  My first Sansa Clip had a few problems with audiobooks, but, overtime, firmware updates corrected most of them, and we each keep two Clips going with audiobooks.  Replacement time is here.  Fortunately, a few old models remain available–at twice the price.  With luck, they will give Sansa enough time to cleanup its faulty software.  I can’t believe the audiobook market isn’t large enough to justify getting the software right.
