Ubuntu Linux Platform for Desktop has been known for its better UI experience without being heavy for the computer and being Virus-free. Yes, it takes time to get associated with that OS because almost all the operations happen with the terminal window. Now let us see that at what features Ubuntu Smartphone OS is targeting.
They will reduce the number of barriers while performing the basic operations on your Phone. For example, if you want to chat with a person on Facebook or GMail or via SMS, then currently you will have to open the different and appropriate applications to do the same, but they will reduce it by creating a common window for all those messaging.Navigating among the applications will be easier, it will be exactly similar to the ‘Zypher’ jailbreak application used in iPhone. Where you can swipe your fingers towards the on the screen to switch to the last application used by you.Minimize the hardware buttons, by removing the Home button (only ‘Power’ button available on the phone). You will only have to swipe your finger towards the right from the left edge of the mobile screen to reach the Home Screen.Home screen will not simply have all the application installed by you, but they will be prioritized by the number of times it has been used you. So, generally a user uses 5 or 6 applications every day and thus they will always be available at the top. The main feature is to increase the ease in the approachability of all the application on your phone.Every functionality will be available with the gestures on your phone.
You can take a look at the video mentioned below to know more about this OS which is being shown on Samsung Galaxy Nexus phone

Conclusion
I personally feel that this smartphone OS will be a good competitor in no time and the best part will be its UI gestures and virus-free environment. But as mentioned at CES this will be released in early months of 2014.
