I see your point. It isn't stinginess on my part but time but more to do with time.
I listen to a lot of audio books when I drive. I buy most online these days via www.audible.com
and the audible app is totally crap. Most books are burnt over numerous CDs (often 8, 9 or 10) and they tend to fade out each disk with an overlap with the next (very irritating).
My car has a CD changer in the trunk (I'll make a concession to American vernacular), but I don't want to have to fill it up with a single book (and then stop the car to reload the cartridge halfway through).
Ideally I want to put the books on a Zen Micro in MP3 or WMA format or make an MP3 disc for a portable player, but there is no way of generating this except for burning to CDs, ripping the CDs and then editing out the overlaps. I have literally dozens of books, so even with cheap media it still works out expensive to burn and chuck discs, and it is incredibly time consuming (even with a fast burner). If I try to save money by using CDRW discs then burning is even slower, plus I have to reformat a lot - even more time.
This isn't the only application which would make this useful for me, but is the main one at the moment.
