OK... but at 45 degrees?

To easily change timezone on an analog display clock? ;-)

I've been in a couple of events in the field where having arbitrary application window rotation would have been nice because there was no place flat to put the monitors.

Non-desk applications: vehicle, industrial, marine.

oooooh, stays steady with the boat pitching/rolling

You don't want that. With the boat pitching and rolling, so does the people on board looking at the instruments, so having the instrument tilt would be rather disorienting! as if sailing by itself isn't disorienting enough. ;)

Yes! I meant more, you have awkward spaces to fill and it may be convenient to mount a panel at some odd angle but still have it display things aligned with the floor.
