I have an IPod with large storage from over ten years ago. It has worked as a stand alone music alternative to my IPhone very well for all those years when occasionally needed. I think that this is what I like about Apple products — they just work and not for just the first 36 months after you buy them.
The Win products may have had functional batteries and power sources but their Bio, Operating Systems and the like get to about four years and you might as well throw it in the trash as the new systems make the hardware obsolete so fast.
I have a 4GB Apple iPod 2005 model, still works fine 14 years later. I have it hooked up to an ion Pathfinder II portable boombox where it excels as a jukebox. Only upgrade I did was to swap in a Hitachi 4GB hard drive long ago, and a new battery a few years ago. I expect it to work fine for many more years.
