:-) Cards fail, and removing them once the case is off, without causing
damage, was also a 'use case'.

What about gluing MicroSD's into its sleeve/converter that very often is
included in the original purchase?
Essentially building a full-size SD card out of a MicroSD.
Not our first choice, but the reason we are forced to consider this hack
(despite our distaste for sleeves/converters that sometimes fail) is that
full-size SD's are increasingly harder to procure -- as these are no
longer mass-market items: the increased price of full-size SD's can
(sometimes) destroy viability.

machines, and because of their size and 'formatting', virtually zero use
outside of them. Manually monitoring the machines state also works when
they are used mainly in classroom settings and are 'assigned' to specific
students. Very few of our user base have the ability to quickly take a
case apart, or know how to repartition cards that use unix file systems.
Since there are also few devices in the environment which can take a native
full size card, the trouble to steal them, is usually more than it's worth.
