No, you guys got it wrong.. Ha ha..
They use keyboards identical to the English ones we use. I lived in China for 7 months and can't remember ever seeing one that looked like the pic above.
Pin Yin is entered in using a normal English keyboard. When Chinese simplified language support is installed into Windows XP, you see a small button appear at the lower right side of the monitor. Then, when you click on it, you can select cn instead of en. When you start to type in a web page, you will see a popup box appear and you will notice that what you are typing is going into the popup box rather than the site form. Each time you enter a word in pinyin, you will see a drop down list of Chinese characters appear and you click on the character you want from that drop down list. Then the Chinese character will be inserted into the form. Chinese people can enter characters real fast because they have the order of the characters memorized in the drop down lists, and they type the number corresponding to the character rather than click on it.
It's a bit difficult to use when you don't understand the Chinese language. It would be better to just install Chinese language support in the browser and cut and paste chinese words from Chinese dictionary sites if you're trying to buy Chinese IDNs.
