His experience is very shocking, he can not buy a HP or DELL computer with a legal copy of windows installed on it in GUANGZHOU.
Actually, the laptops I tried out were almost all Dell + Lenovo (I wanted a thinkpad or XPS). I think, as another commenter said, they were probably Linux + FreeDOS systems originally.
What the store owners would do is use Norton Ghost to put whatever (illegal) OS I wanted on there.
I think bgee was saying that their side of the argument (that legal Windows is available) is not based on experience.
Or maybe he had an experience not reflecting the reality, which often happens when someone fails to overcome the language barrier.
I speak Chinese and I was with my Chinese wife. Thanks for the patronising attitude though :P
