Query: I have had almost zero problems with this

This product has performed as expected for me and I have not had the software problems that some others obviously have experienced. I have also found the product easy to use and it works perfectly with my laptop. I had some issues with setup, but nothing that I could not solve myself with some general monkeying round. I have about 16GB of music loaded on mine and it works fine every time I use it. My only complaints are battery life seems a bit short and the manual is not very good. Also, I agree that the design is not as attractive as the ipod. Overall I'm very satisfied.
