According to Canonical, it would provide an uncompromised Web 2.0 experience: Web browsing, email, media, camera, VoIP, instant messaging, GPS, blogging, digital TV, games, contacts, dates/calendar, simple software updates will be available periodically. Ubuntu Mobile Edition will only need a touchscreen device and a finger for navigation.
In June 2008, Ubuntu Mobile 8.04 was released. Ubuntu Mobile ended active development after 9.10 Alpha 6.
The development of Ubuntu Mobile has stopped, but Ubuntu continues to work on mobile distributions such as Kubuntu Mobile or the ARM version of Ubuntu.
Since the October 2011 Ubuntu Development Summit (UDS), there is new mobile interface in active development. In 2014, Canonical plans to release Ubuntu for mobiles, tablets and televisions alongside already existing Ubuntu Desktop and Ubuntu Server. This means creating a universal interface, that would adapt its shape according to the device it runs on. Mark Shuttleworth, the founder of Canonical, said the interface is going to be based on Unity (actual desktop environment, developed by Canonical in 2010).
Kubuntu Mobile is available for i386 and ARM platforms and uses the KDE Plasma Mobile. Plasma Mobile is targeted at smartphones and small tablet devices that are mainly used via touch input. It is still being developed with the first stable release expected to be due in 2011, although individual KDE applications may be released earlier as part of the porting effort to MeeGo. Preview releases of the Kontact applications and a document viewer based on Calligra are already available.
