A spokeperson for Intel-Pacific had already said Intel was working with Google, and El Reg got it confirmed straight from Intel's headquarters in California. "We've been privy to the project for some time and work with Google on a variety of projects, including elements of this one," Intel said, "We welcome Google's move here."
It seems like Intel has really come a long way since the days of the whole "Wintel" thing. Not only did they welcome Mac OS X on their chips, they're now also working on various incarnations of Linux; the company's own Moblin effort and now Google's Chrome OS. In addition, rumours are popping up that Intel is also working with Google on bringing Android to their MIDs. The company didn't want to comment on that.
Apart from Intel, Google's got some serious companies backing the Chrome OS effort: Acer, Adobe, ASUS, Freescale, Hewlett-Packard, Lenovo, Qualcomm, Texas Instruments, and Toshiba, among others. Let's hope Google's Chrome OS efforts bring more diversity and competition to the marketplace.
