Google Translate has always been one of the unsung heroes of the free service space. On the one hand, it doesn't provide a perfect translation, so people are still hesitant to call it a true breakthrough. On the other hand, we use it all the time to translate web pages enough to get the gist and, when combined with speech-to-text and text-to-speech, you can use the Android app as the closest thing to a universal translator in your pocket the world has ever seen.
