Linux-based Ubuntu OS for phones announced, will be arrive in early 2014 

 

Linux-based Ubuntu operating system. Just like the Android OS, Ubuntu for phones uses the same basic kernel and drivers but has the brand new User Interface and navigation. A short swipe from the left shows your favorite apps.A long swipe takes you to all your apps. Swipe from the bottom shows you the menu controls for the app you’re in.A swipe down from the top shows you your notifications and messages. Ubuntu places heavy emphasis on HTML5 web apps and gives them high priority, wherein they can show you notifications just like native apps. If you want an even better experience, you can also use the native apps written specifically for Ubuntu.Although it is based on the Android kernel, Ubuntu does not use the Dalvik Virtual Machine that Android does so apps are incompatible between the two. On the plus side, the lack of virtual machine and ability to run apps natively means the performance is likely going to be even better compared to Android
