Case in point: minidisc :)
Recording was the killer feature for me. I recorded thousands of hours of band rehearsals with their stereo omni mics and the media quality.
Gotta love the LP4 mode. So much music on a single disk! Remember the cool rectangular batteries? Why aren't these gumstick batteries more used in modern devices!?
The crazy thing is these came out in 92' and they didn't stop production until 2013 so you can still find these players. I just found out Sony stopped production of the minidiscs just last year which is crazy. A 20 year run for the player and 30+ years for the minidiscs.
If you can find a player, you can still get the discs on Amazon which is awesome considering how disposable tech has become.
