+ Right, right, right, right--the physics doesn't work in left, left, left!!! + Perhaps much of this right/left/up/down confusion is due to graphics books that sloppily switch all around. + The hardware argument has no bearing.

Since coordinates are purely conventional, it would be amazing if physics "didn't work" when one chose a left-handed system. Of course, if you don't distinguish between vectors and pseudo- vectors (best done by using skew tensors, aka forms), you're making a mistake that shows up when coordinate conventions are switched on you; but it isn't the physics that's broken.
