IME means “Input Method Editor” and in this case, is used to convert 汉语拼音 to Chinese characters. The default solution available in Windows is the built in Microsoft IME by choosing Chinese (PRC) as the language. It’s something which I find a little unresponsive, but other than that I can live with it since I do not type in Chinese very often.
Google’s IME has some innovative features, such as depositing users’ personal phrase on Google’s server and synchronize it between different computers. You may also find popular words on Internet would be typed easily and accurately.
Attractive feature isn’t it? Now I need not retrain my IME every time I format my PC! Who needs to pay for HansVision when there is a free alternative! I’m sure this tool would have continual updates from Google since they are eager to compete for more users in China.
