Works fine for the car
My old (10+ years?) one just lives in the car and does a fine job a supplying my music to the car stereo. Every now and again I bring it inside to update it with anything I've bought recently. The sound (with high bitrate recordings) is good enough for the car, as any imperfections are hidden by the road noise anyway.
When it dies I expect it'll be the spinny disk, so I'll just go the SD card replacement route and continue with it until it dies completely.
