Google I/O is one of the stables of the tech calendar. Despite being a developer conference, its keynote usually reveals a host of new features and devices that will be coming later in the year. Much like Apple's WWDC, the keynote then, is a public affair and can be watched by all – before the conference drills down into the real developer stuff later in the day.
In the past few years, the Google I/O keynote has revealed the big new features for the next version of Android OS, as well as advances to popular Google software, such as Google Maps, Google Translate, and Google Search.
