Still no 12".
The notable changes:
- 2GB RAM (2 DIMMs) is now standard across the line (thank heavens!) and is now upgradeable to 4GB.
- 8x SuperDrive is now standard across the line.
- Apple claims up to 6 hours of battery life on the 15-inch model as compared to 5 hours on the previous one and 5.75 hours on the 17-inch as compared to 5.5 hours.
- On the 17-inch model only, it is possible to get an extra high-density display with a resolution of 1920x1200 as compared to the regular 1680x1050.
- The graphics engine is now powered by a NVIDIA GeForce 8600M GT.
- The physical dimensions of the machines haven't changed at all except for the 15-inch model's weight which is 5.4 pounds as compared to 5.6 pounds on the older models.
- LED-backlit displays that are lighter and conserve power (I want to see if these feel any different in real life).
