Canonical on Tuesday announced a new version of its Ubuntu Linux operating system for tablet devices. The operating system supports multiple user accounts from the home screen, including a “guest mode” option, and uses gestures to navigate around the user interface. It also features a notification center, sharing to all major social outlets, extensive multitasking support and is capable of displaying applications designed for both tablets and smartphones simultaneously, similar to the Snap View feature in Windows 8. Canonical plans to offer a developer preview of Ubuntu on February 21st for Google’s (GOOG) Nexus 7 and Nexus 10 tablets, along with the Nexus 4 and Galaxy Nexus smartphones. A video demonstration of Ubuntu follows below.
