http://www.appleinsider.com/article.php?id=2426 They seem to be moving from cold cathode fluorescent backlights (CCFLs) towards LED backlights. "While pricer than CCFLs, LED technology is more efficient at distributing lighting evenly across the entire display surface and offers an increase in color saturation. According to a white paper from Cree, a backlight solutions provider expected to provide its LED technology to Apple, LED-based backlights also consume less power, run cooler, and last longer than CCFLs." Sounds good to me. Just sold my Macbook so I even might wait for 2nd quarter of this year before buying a new one.
