Hello Foss Folks ! Ubuntu as you know is going through a lot of transformations both in mobile devices and desktop computers. For Trusty, Beta 1 is out for Ubuntu flavors and are available for testing.
The daily image for Ubuntu 14.04 is here. If you want to see the changes in Ubuntu with Unity, simply download a daily-live image from above link and run the same in Virtual box. We will not suggest you do a dedicated install in your regular machine, though it is stable than before, still has glitches.
Stay tuned, we will keep you posted.
Njoy testing !
