The iPod classics are also wonderful single purpose devices that last a long time, and are quite upgradable. The software is much simpler than an iOS device, and can be changed to the open source Rockbox. You can replace nearly all the older components with cheap Chinese parts eg shiny new outer case, higher capacity battery. Then add a new circuit board so the iPod can use high capacity micro SD cards instead of the original hard drive. The result is all the advantages of the original iPod, with more storage capacity and insanely good battery life.
