Every couple of years, I buy a used Sansa Clip+ from ebay to replace the previous one that suffered physical damage. I transfer over the 128GB/256GB sd card. Voila - entire music collection in the size of a box of matches, no need for data connections, or a working phone, or fumbling with a screen when I'm working out.
SHHHHHH!!!! Don't tell people that or pretty soon we won't be able to find them any more! ;)
Seriously though, seconded, but also install Rockbox: https://www.rockbox.org/
But seriously, this illustrates to me that Codes of Conduct are mostly suspect. This is obviously a private feud (nobody looks to be in the right here and I don't care who started what), so to pull "they violated the CoC" is pure theatre and bullshit. I'm a Sparkfun customer and I find that really disappointing.
