Google begins serving up KitKat upgrade to some Nexus tablets

Owners of the Wi-Fi-only Nexus 7 and Nexus 10 slates can expect the next version of Android to begin rolling to their devices Tuesday night.

Some Nexus tablet owners can expect to get their first taste of Android KitKat soon.

Google announced on Twitter Tuesday that it would begin rolling out an over-the-air upgrade of Android 4.4 KitKat to Nexus 7 (2012 and 2013) and Nexus 10 tablets immediately.

However, not all Nexus owners can expect the upgrade right away; Google said the current rollout is for Wi-Fi-only tablets, meaning that Nexus slates with mobile data will have to wait, as will owners of the Nexus 4.

The latest version of the mobile operating system, which Google rolled out last week with the debut of the Nexus 5 smartphone, doesn't pack a ton of transformative design and feature changes like the Ice Cream Sandwich update. Instead, KitKat's main purpose is to usher in a strategy toward minimizing fragmentation, a problem that has cropped up because of the wide variety of Android devices on the market running different versions of the operating system.
