Here comes Lollipop

Behold, Android 5.0 Lollipop has started its long-awaited deployment to Nexus devices. Grab your Nexus, be it a Nexus 5 or a Nexus 7, or perhaps even the new vanguard the Nexus 9, and check thee for an update. It might be there, it might not. But it's coming, starting now.

At least according to Google.

We're keeping an eye out for the Lollipop factory images and will let you know when they hit in case you really don't want to wait. In the meantime, we suggest brushing up on how to manually update your Nexus device.
