Intel has started full production of its Oak Trail platform for Atom-based tablets, insiders said Wednesday. The first processor to ship in the Atom Z600 series should be a Z670 running at an unknown clock speed with one Oak Trail chipset, SM35, to keep it running. Price would be the focus as the combination would cost about $25 when using Intel's in-house MeeGo platform, Digitimes tips said, with Microsoft's relatively expensive Windows 7 adding more.
