micro SD cards were a bad move
SD card:
- physical write protect switch
- uses a spring loading mechanism. nice satisfying click
- big enough to feel like an object
- but still plenty small
micro SD card:
- oops accidentally deleted my data
- removed with an unsatisfying plastic fingernail ridge. no satisfying click. is it in place? who knows
- where is it? I don't see it
- oh there it is. better not sneeze
