What does SVR3 have that SVR2 doesn't?

[Larry Campbell]

I am interested in a _concise_ description (extra points if it fits on one
screen) of what's new in SVR3 (besides streams -- I've already read the papers
on that).  The question I'm really trying to answer is, given a choice
between SVR2 (for perhaps less money) and SVR3, why should I choose SVR3?
