Let's discuss what fixes for the rMBP the 10.8.3 brings. What I noticed (15" rMBP):
1. Most notably - Mission Control. On 10.8.2, dragging items (like big images) between applications was very choppy with Mission Control, now its extremely smooth.
2. Safari seems slightly faster. No idea whether they fixed the input boxes and garbled rendering.
3. Wake-up from sleep seems to be much snappier (on 10.8.2, it took longer to wake up from sleep than to actually boot the machine).
P.S. There still seems to be slight input lag in Safari :/
