I have two MacBooks running Emacs (both 24.3). On one of them, I get same smooth, native scrolling like I do in Chrome, Finder, or whatever, but not on the other one.
To make it work a bit better, I set up scrolling so that it only scrolls one line at a time. The proper one scrolls pixel-by-pixel, and with the acceleration I'm used to.
Both of these computers use the same set of dotfiles (which you can browse here), e.g. Emacs – including the stuff about scrolling – is configured in exactly the same way.
Not sure if it matters, but one of these MacBooks (the one that works properly) is a 15" Retina one, the other is an older (mid 2009) model.
I have tried Emacs for OSX and emacs-app from Macports, both of them have the problem.
What am I missing?

I still have no idea how I managed to get it working on the Retina MBP, but I found this version of Emacs which supports native scrolling, much nicer full-screen mode, and more.
