observation: what's good about microSD cards

MicroSD cards have their drawbacks, mostly being too easy to lose because of their size; but I'll tell you what I like best about them: they're as easy as optical disks to destroy (for security) if they fail. After a year or so, my 64 GB microSD card went dead and I couldn't revive it; so I just tore/crumbled it up with a few twists of the finger and threw the bits away. No need to bother with scissors. I can never do that with a dead hard drive.
