[UKids] Glueing SD cards into XO laptops

Adam, we tried silicon over the slot applied from the inside, not glue.
 :-)  Cards fail, and removing them once the case is off, without causing
damage, was also a 'use case'.

What ended up being a more reliable method to prevent theft, was not using
micro-SD's in adapters, but only full size cards.  Then, one educates the
students that the cards have great value in the 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.

Depending on your user stories, to quote the vernacular, your mileage may
