A very good source is Murray Sargent's blog:
e.g. this (quite technical) post:
"The new font tables enable one to automatically position subscripts and superscripts horizontally better than untweaked TeX as well as having richer glyph choices for operators like the integral sign, square root, and growable brackets."
"In addition math characters have four cut-in values, one for each corner, allowing sub/superscripts to be kerned with their bases."
TeX, on the other hand, (ab)uses the italic correction for superscript/subscript positioning, which is not as flexible as the OpenType approach.
