Lithium ion batteries tend to degrade over time too.
But I had a kindle 1st gen I got off ebay I used a little that I abandoned after I broke the screen. I was one of the many who lost network connectivity, though, presumably through Sprint action. Wouldn't surprise me if they discontinued their 3g network and shut down 1xRTT in my area, leaving 2g voice-only. (CDMA 3g is data only and Sprint is CDMA)
