Sogou just launched a cloud pinyin input application enabling anyone to type Chinese inside browsers without any software installations.
Sogou Cloud Pinyin input is based on JavaScript technology, Ajax, and cloud technology. Without any installation, one can input Chinese on any operation systems. It is compatible with all major browsers (IE, Sogou browser, Firefox).
Simply go to this page and then drag the icon (as the one shown above) to your status bar; click on it whenever you need Chinese input. The speed is not perfect, slower than desktop applications. And, it doesn’t work well in email when I tested.
This is a very innovative product from Sohu (whose search product is called Sogou if you don’t know) and it’ll further its Pinyin Input market share by penetrating to Mac and Linux users.
