GA.....while my feelings aren't as intense as yours seem to be,......I hear ya. I feel a little misled. I am sure the company and the retail outlet would make it right (I bought mine at Staples, and am sure I could get a refund), but that misses the point. I specifically looked at the back of the package (remembering that the m200 read .aa files, and advertised that fact) looking for Audible Compatible, and now I find out it isn't. My wife's player (the m200) plays the .aa files, and we have purchased about 2 dozen books from Audible, and have a pretty varied resource of books at my disposal...IF, it would read them. In my case, it is no big deal. I like the player, otherwise, and have other options for the books, but it just is disappointing now that I have it, that it doesn't match the proposal. I am willing to accept that some underling at Sandisk was in charge of handling the write up on the back of the package, and they just used what was on the back of the m200 when they released the c200 series. It probably slipped thru the cracks. At best, it is just sloppy and unprofessional. As stated, not a deal breaker for me, just not as happy a camper as I otherwise could have been.
I guess I am done commenting now, on it, and will get on with life!!!
