Apple left a little mystery in their MacBook Pro announcement today, and being that this marks their first official release of an LED-backlit laptop we had to take out the guesswork and get confirmation on a few of our more burning questions.
All 15-inch MBPs now use LED-backlit displays standard; 17-inchers still use CCFL (cold cathode fluorescent)
Apple claims users can see a battery-life benefit of between 30 mins - 1 hour (depending on use). They did not have stats on exact efficiencies between LED and CCFL backlit displays.
The new LED backlight is the same brightness: 300 vs 300 nits of the previous gen's CCFL
The viewing angle is also the same as before
In other words, besides faster time from fully-off to full-brightness and an increase in battery life, Apple claims users should notice absolutely no perceivable difference between last-gen displays and the new LED-backlit ones.
To clarify, MacBook Pros are using Santa Rosa, but MacBooks are not yet using Santa Rosa
Even though the MBP is 0.2 pounds lighter, we're still without an internal / integrated 3G option
