A comparable Everex PC with Windows with Vista Home Basic would cost an additional $99 'partly because the manufacturer has to pay Microsoft Corp'. This gOS is 'heavily oriented toward Google's Web sites and online applications'. It will be available online, and at about 600 stores in the U.S. I wonder why Wal-Mart's Canadian customers have been deemed unworthy of a free operating system on their PCs.
