I recently found a 90 minute cassette from 40 years ago with some good obscure music I had forgotten. The accessibility and touch of the cassette and a floppy interfacing with the player or controller gives a better tactile feedback then a USB disk or MicroUSB disk. You can more easily loose the USB disks as well as they are smaller and don't really make noise when dropped.

As MiniDisc and Zipdrive are obsolete I'd like to have a minicd or businesscard CD audioplayer based on a RaspberryPi Zero. With using Vocos, EnCodec or Lyra v2 you could fit 200 hours of stereo audio on the small cd at around 3 kbps and select them with some buttons and a LCD screen. Similar to the Imation RipGo or Memorex portable 8cm mini-cd players which could play mp3. https://languagecodec.github.io/

Alternatively I could use cassette or microcassette. https://hackaday.com/2021/10/20/audio-tape-interface-revives... https://blog.adafruit.com/2023/10/17/a-wind-up-cassette-play...

I could run a bootable OS on MicroSD and using external small cd's as data or app storage, perhaps also to boot from. An OS experience [Redox, Haiku, KolibriOS, Dragonfly, Fuchsia, MorphOS, Serenity] booting from a 8 cm business card CD depending on the day, weather or mood. https://en.wikipedia.org/wiki/Mini_CD

Or perhaps just boot into a Raspberry Pi zero menu to select or boot a random OS from the Zero and use Airtagged encrypted USB-C sticks (making sure each OS can read the encrypted volumes).

Bootable business cards have been around for a while. Eg

CD based: https://en.m.wikipedia.org/wiki/Bootable_business_card

PCB based: https://hackaday.com/2019/12/24/now-even-your-business-card-...

There’s also NFC based digital business cards, which are now really common. But they’re obviously it bootable / running Linux.
