When Microsoft showed off Windows 10 Phone's Continuum feature at Build last week there were many who were quick to point out the Ubuntu was there first. Only it isn't yet, as Canonical haven't got anything approaching this capability into Ubuntu yet, has only shipped one low end handset with an near unknown OEM and does't have anything like the funding necessary to compete with the Microsoft division formerly known as Nokia.
Mark Shuttleworth, point man for all things Ubuntu, claims that he intends to beat Microsoft to release, even with all these challenges.
That's a ballsy claim considering all the challenges. Given how far Ubuntu has come in just over a decade I wouldn't bet against Canonical pulling it off.
