Thought I'd see if there were any likeminded individuals around.
This is three of my small collection that I have with me at work. The 4G Classic (left) is modded with 64gb, the Mini is 128gb, and the 7G Classic is currently in need of storage and battery. My plan for that one is to give it 512gb and as big a battery as I can squeeze in there.
I have an ipod mini HP from 2005 - it looks like it's been chewed on by a dog but the DAC sounds so good... It was modded to have a new battery and 64gb storage.
Can we mention our other MP3 players? I also use a Sandisk Sansa-clip, pretty good sound quality and battery life for an off-brand nugget. (Also still holds a charge a long time for something from 2011)
