Canonical is promoting the concept of phone and PC convergence for Ubuntu Edge, but until now, there hasn’t been a proper demo of this technology.
Ubuntu for Android was announced over a year ago, but the development hasn't been advertised seriously until the appearance of Ubuntu Edge.
“For over two months I’ve been running Ubuntu for Android on a Nexus 4 phone, and even with its much slower processor and smaller storage than the Edge will have, it’s still made my working life so much simpler. With just a phone I can do pretty much anything that I could do before on my laptop,” stated Canonical’s Victor Palau on his blog.
You have to keep in mind that the software is still in its beta phase and it’s not the final quality of the product. Ubuntu for Android is demoed on a Nexus 4 which is inferior to the proposed specs of Ubuntu Edge.
