I love this cd player, I got it for christmas and I think it may have been one of the best things I got! My old Personal CD Player was hardly used, as I found it to bulky but as this one is so small it fits perfectly into my handbag, so it is easy to carry around. The battery unit is stored inside the player, but that is not a problem as I use my cd player about an hour on average everyday and I have not had to change my batteries yet! Also there is a battery display on screen to tell you when your batteries are running low. As for the Atrac technology I love it, so far I have taken my faveourite songs of my albums and loaded them on to the cd, therefore I do not have to carry my cd collection everywhere with me. As for the software I thought it would be slow but I was surprised how quickly it transfered all the songs. I would say that if you were'nt bothered about getting a small MP3 player than this would be the product for you!
