As some people on OS X mailing list noticed: Lion (and the new Safari
that might even work on Windows) now ships STIX fonts (without math
tables) and supports MathML. Sadly they probably don't support native
OpenType Math fonts.

Another interesting bug report:

Ulrik's article)

Why sadly? You are paying for this OS and as a customer you must demand
what you are looking for. Or else switch to some completely Open OS and then
you are "free" to say---sadly :-)
