The improved Chinese/English/Pinyin support looks interesting.
From Apple.com: With improved text input and built-in support for popular Chinese Internet services, iOS 6 makes iPad, iPhone, and iPod touch even better for Chinese-speaking users. With a new Chinese dictionary and improved text input, typing in Chinese is easier, faster, and more accurate. You can mix full and abbreviated Pinyin and even type English words in a Pinyin sentence without switching keyboards. With support for over 30,000 characters, iOS 6 more than doubles the number of Chinese characters supported in handwriting recognition. And when you add words to your personal dictionary, iCloud makes them available on all your devices. Baidu is a built-in option in Safari, and you can share videos directly to Youku and Tudou. You can also post to Sina Weibo from Camera, Photos, Maps, Safari, and Game Center.
