Query: Beware Long-term Durability

iRiver is known for poor quality. Buttons break frequently. You will be happy for one year(sound quality is good) but, then the device will break. iRiver does NOT stand behind their product. They, apparently, depend upon breakage to generate new sales. Additionally, they sell at higher prices than their competitors - and give lower quality.Look at Consumer Reports November 2004 issue. It will be clear to you which products you should be considering.
