Google releases Android 4.4.3 factory image for the Nexus 5

In an effort to create a balance in the force, Google has dropped the Android 4.4.3 image for the Nexus 5, Nexus 7 (Wifi-only for now), Nexus 4 and Nexus 10 on their downloads page. It's a 444MB download, and you'll need fastboot set up to install it. We've not yet seen any OTA updates, but we imagine they are coming if you'd rather wait.
