Clear message

This project is no longer maintained. You might be interested in Ubuntu Touch though.

It’s time to look at the core of Ubuntu and review it through a mobile lens. During 13.04, we will like to measure and improve how the guts of our platform performs against mobile metrics.

Things like battery life, memory footprint, support for sensors... are areas where needs and expectation widely vary between a PC and a mobile devices. 13.04 will be a cycle of exploration and learning. Because there is no better way to learn that getting your hands dirty, our practical exercise will be to get Ubuntu Desktop working on the Nexus 7.

The Nexus 7 exercise will be less like a 100 meters sprint (if you don't cross the finish line you don't get a score) and more like Javelin competition. The further that we can throw it, the higher the score!

On those basis, here are 8 types of Javelins to throw and some distance markers to hit for Ubuntu Desktop on Nexus 7:
