In fact, I would go so far as to say Canonical was quite premature in the releasing of devices. You see, this whole schmear isn't going to spread properly until Unity 8/Mir is released. At that point, everything changes. Once the Ubuntu desktop is in conjunction with the phone/tablet space, everything will be running the same platform, the same code. That is when things get interesting. When we finally see phone/tablet/desktop running the same release of Ubuntu, we'll see convergence finally work as it should. Why? Because all those apps we depend upon (LibreOffice, Audacity, Gimp, etc) will run on the convergent platform.
