You know MacWorld is here when Apple rumors start to hit CNBC: According to a report by Jim Goldman, Apple will launch a ultra-portable sub-notebook in San Francisco this January. Citing sources "close to manufacturing, "Goldman says it will be 0.5-inch thick—half a current MacBook Pro— and use a flash-based solid state drive instead of a regular hard drive. Still conscious? He says it will be available for $1,500 with a 12-inch screen, although AppleInsider stands by their 13.3-inch display story, which is in line with previous LED-backlit screen rumors.
