Victor Palau, the Commercial Engineering Director at Canonical, uploaded a video on Friday of Ubuntu on the Nexus 7.
The Nexus 7 was developed by Google in conjunction with ASUS as an Android tablet, but Canonical found it to fit well for Ubuntu. The 7.81-inch tablet is based upon a NVIDIA Tera 3 SoC with quad-core Cortex-A9, GeForce graphics, 8 or 16GB of flash memory storage, and 1GB of RAM.
Below is the video of Ubuntu (with the Unity desktop) on the Nexus 7. Expect more details to surface at month's end from UDS in Denmark.
