Macworld Expo: Ultra-portable Apple laptop 50 percent lighter

The ultra-portable Apple laptop rumor is now being mentioned by AppleInsider and they claim that this laptop could appear at Macworld Expo in January.

The ultra-portable laptop is said to be 50 percent lighter than Apple’s current 15-inch MacBook Pro and should sport a 13-inch display.

Other features claimed are NAND flash storage, a much slimmer design, considerably more power-efficient and an LED-backlit display.

This rumor has a date on it (Macworld Expo in Jan 08) so this could be good, do you think AppleInsider could be right?
