Canonical, the company behind Ubuntu, is hard at work on Ubuntu Touch ? an operating system aimed for smartphones and tablets. Theyve even released some images that can be installed on the Nexus 4, the Nexus 7 (2013 WiFi only), and the Nexus 10. Theres also unofficial support for the Nexus 5, which we reviewed, and Nexus 7 (2013 WiFi+LTE). If you dont have any of these devices, dont worry ? you can still try out the mobile operating system using an emulator on your Ubuntu computer.
