Twinhead announced at CES that its DuraBook line of toughened notebooks would receive an upgrade to Intel's more recent dual-core processors. Originally introduced in 2006 with mobile Celeron and Pentium processors, the latest DuraBooks now have the option of Core Duo or Core 2 Duo processors and receive upgrades to storage and wireless: both the 13.3-inch widescreen D13RY and 14-inch standard-aspect D14RY ship in base trim with a 1.66GHz Core Duo, 60GB hard drives, and added support for 802.11a Wi-Fi to complement existing b/g options. Both systems retain the military-grade magnesium case design, which the company says is 20 times stronger than standard plastic. Pricing is unavailable, though Twinhead promises to ship both DuraBooks soon.
