In reply to supersteve:
I still use an iPod Nano - I bought a couple of second hand ones off ebay in recent years after my first one started to not work so well after about a decade of daily use being in my pocket. I just listen to podcasts though, not music, so am quite happy with one ear bud in.
When I'm on long bike rides I use my phone for navigation, tracking and photos as well as communication! So I'm happy to have a second widget just for podcasts - it can hold many hundreds of hours of audio, and the batteries last really well at least when listening to podcasts at a relatively low volume. I also bought a plastic case for the first one I ever bought and still use that case! I've dropped it loads of times while riding my bike, and in that case totally failed to break one. I might go backpacking for a few days or bikepacking for a similar time, and not need to charge the iPod at all despite listening to it all day, or perhaps give it 20 minutes connected to my charger to fill it back up again.
I imagine sooner or later my current one will pack up and I fail to find a replacement on ebay for a sensible price, and go over to using my phone for podcasts as well, but until then I'm perfectly happy to carry on the mid-noughties legacy!
