I still use my 1st Generation shuffle, I grab audiobooks from YouTube, import them into iTunes, and transfer them to my shuffle to listen to while I'm working in the yard. Shockingly the thing still holds a pretty good charge, hours of use before the battery runs out. Anyone ever replaced a battery on one of these things? I see it can be done on iFixit, but I don't know if I'd have the skill to do it myself.
