Most Chinese computers had a LINUX OS? Can't imagine how anyone could ever get such an impression. Windows is very much king here, and as others have indicated you're probably best served in China using a computer with this Mark of the Beast upon it.
actually, a lot of computers "ship" with Linux as an OS because the new rules as of last year state that no computer can be sold without a legit copy of an OS. As soon as they "sell" them, they install a borrowed copy of windoze on it!
Some of the ads I've seen in Beijing lately are even advertising computers with MS Dos as the operating system
