I sent my hd-5 back cos it had crashed and died. The person I spoke to did his best to convince me not to send it but I sent it anyway cos a dead unit is no good to anyone (especially a 6 month old dead unit). It had also developed the cracks on the buttons (after about 2 weeks use) which I mentioned in the cover letter and they proceeded to ignore.
So overall, although I got the unti back in less than 4 weeks they did the minimum work required to bring it back to a working state. I must also say that although I live in the anti i-pod world, the build quality of the hd-5 compared to the i-pod is very poor. You only have to hold an i-pod to notice. Even with you eyes closed
saying that i am a happy bunny cos i got my player back before xmas and I didn't think I would get it back till the new year.
