The specs he lists on the iBook (or “IBook” as he calls it) would draw a lot of people in if they were true: dual-core Yonah processor in the 1.5 to 2.0GHz range with a 667MHz front side bus. The new IBooks will ship in a single 13.3-inch widescreen (possibly High-Def) configuration..
I have a small page tracking some of the more relevant rumors – Apple Mac/Intel Watch
Macworld starts on January 9th.
