Googles making its Chrome OS work better for people with Android devices. A new feature announced at its annual I/O developer conference today lets users unlock their Chrome OS device using their phone automatically. The changes come as Google plans to make Chrome OS work better with Android apps. Google today announced support for some Android apps right on Chrome, including the option to launch Android apps through the Chrome launcher. Googles effort joins one announced by Apple earlier this month that lets users send data between iOS 8 devices and computers running its upcoming OS X release Yosemite.
