For me, it's to debug code in an embedded system (ie. a computer inside a
widgit like one of our robots or, for others, things like appliances or
industrial stuff). Such systems usually lack anything resembling a GUI. So
you plug one of these pods into the CPU socket where it stands in for the
CPU or a special connector on the CPU that lets it spy on what the CPU does
inside. The result is displayed on the "host" screen (ie. on your PC),
allowing you to start and stop the CPU under test and fiddle with the
variables inside. Good ones will keep a trace of the last things that
happened (with the price going up with the depth of the trace) allowing you
to look backward in time to see what led up to some anomalous condition.
Sometimes it can take hours or days to manifest a bug, so trace is
invaluable in doing a post-mortem to see what actually causes it.

Whoa, that's way beyond anything I'll ever have a need for.
THANK GOODNESS!!!! ROFL
It makes total sense, though, as a whole lot of things have computer
components in them. Look at what's happened under the hood of any
automobile in the last decade or two. And my Roomba vacuum- it's
got to have some sort of computer in it to guide it around, or "see" the
spots it thinks are heavily soiled so it makes multiple passes.
Thanks for more education!
