I'm pretty particular with the condition I keep my gadgets and books in. So it surprised me to come across this:
An Amazon Kindle 2 USB charging cable, left intact and still wrapped in its original wire tie, after 2.5 years. The cable sustained cracks all over the place. It appeared that the cable cover has become brittle and chipped away. Keep in mind that this cable has never been abused or even moved around extensively. I can understand if the cable sustain such wear from abuse and harsh usage, but this cable has been stationary for the most part of its existence. My iPod Touch (2nd gen) USB charging cable began to crack, but only at the joint between the cable and the charging connector, and after much abuse.
