Asus has started rolling out an update to Android 4.2 Jelly Bean for its Transformer Pad TF300 tablet.

The software update means that the Transformer Pad 300 is the first tablet to get Android 4.2 Jelly Bean aside from Google’s Nexus 7 and Nexus 10. Asus is rolling the firmware out in the US from today and other regions during March.

In a time where Android 4.2 is still a rarity for those who don’t own a Nexus device, ASUS has come along and, once again, put a lot of OEM to shame with swift action on the latest version of Android.

Along with all of the goods Jelly Bean 4.2 brings, including widgets on the lock-screen and user profiles for multiple users, ASUS will also have significant updates in tow for its App Locker, its virtual keyboard, the lock-screen and setup wizards. Users can grab the upgrade over-the-air so be sure to take a quick trip to the Settings > About Tablet menu where you’ll be able to pull this one down.

In related news, ASUS has confirmed several other tablets in its lineup that will get Android 4.1 in the second quarter of this year. These tablets include the Transformer Pad Infinity, the ASUS MeMO Pad Smart 10, and the MeMO Pad.
