That was quick: it took Sony just a day to give Xperia Tablet Z an Android 4.3 AOSP ROM
Sony is the first manufacturer to announce Android 4.3 upgrade plans for Xperia Z, ZL, ZR, Z Ultra and SP, but also for the Tablet Z. As if to prove how quickly it plans to do the upgrade of its flagship devices to the latest version of Android, it already ported what Google released yesterday on the Tablet Z, in the form of an AOSP ROM.
It is not yet suitable for a daily driver, Sony developers warn, but still pretty functional as you can see in the demo video below, so if you are interested, hit the repos in the source link below.
