This is also just anecdotal, but I used to work with a Chinese sysadmin (I was in the UK, he was in China) who found it much more preferable to work on the localised Windows servers we had installed over there, as all the UI and messages were in his native tongue. I'm sure it was easier for him to gain expertise in the tools he needed for his work, than to become proficient enough in English to understand every obscure log or error message that the system might throw at him.
