The Macworld Feature MacBook Pro: What you need to know has the facts on how the new MacBook differs from the old PowerBooks. Differences include the ports, battery, thickness, optical drive, RAM — oh, just about everything. I’m looking forward to having more nits though:
The MacBook’s display is slightly shorter than the PowerBook’s—60 fewer vertical pixels than the 15-inch PowerBook. But it’s also much brighter, going from 180 nits (a standard measurement of brightness—or luminance—whose name comes from the Latin for “to shine”) to 300 nits. The end result is that the screen is the same brightness as Apple’s Cinema Displays.
Better find my sunnies!
