Re: Putonghua
These days only the Taiwanese (& Aussies & some others of us) use the term 'Mandarin' - the mainalnd Chinese call it Putonghua
Putong Hua - 'Common language' (Putong = language or speaking , hua = of the people).
Still need time to learn the Putonghua 'get stuffed' stuff (Cantonese is full of how to tell people to get stuffed in a multitude of ways & every thing else).
But Billy 'n Bally are "Fukeee upee'd" as far as China is concerned :-) :-)
Question then becomes 'How relevant is the Chinese OS market' - my response is 'Watch this space' :-) :-)
