Apple is reportedly developing a miniature sub-notebook, and is expected to re-establish itself as a leader in the field of compact computing as it reminds the world of its renowned PowerBook 2400. AppleInsider reports that despite the 10 years since Apple offered up a sub-notebook to consumers, the company is planning to unveil a new mini MacBook that promises to be everything a modern day PowerBook 2400 should be and more. The new MacBook is expected to include several features not yet available in Apple's existing notebooks, such as onboard NAND flash memory to improve power efficiency and provide nearly instant boot times. Apple is hopeful that the new portable will help sales in the Japanese sector, which are on par with industry trends but continue to fall -- dropping 14 percent year-over-year for the first quarter of 2007.
