For the first time in its history, Canadian smartphone maker BlackBerry has launched a device running an operating system other than its own.

On Tuesday Google not only unveiled two new flagship Nexus smartphones and two new Chromecast devices, but it also showed off a new Android-run tablet to compete against Apple’s new iPad Pro.

Google is countering the release of Apple's latest iPhones with two devices running on a new version of Android software designed to steer and document even more of its users' lives.
