According to Forbes, Austek has been contracted to build 1.2 million Intel-powered iBooks with 13.3 widescreen displays (the displays are from AU Optronics Corp, Chi Mei Optoelectronics Corp, and LG Philips LCD). No word on if it’s Core Solo or Core Duo. These have been rumored for quite a long time, and this is the first solid evidence we have of them.
They are expected to ship to customers in June. It’s safe to assume that they will have the same dual-boot capability (Windows and Mac OS X) that current Intel-based Macs have.
