Everybody already carries a computer that powerful around with them continuously -- their phone. And that phone is powerful enough to run office applications, web browsers and video games.

Soon every monitor will be a docking station for both phones and laptops. A USB 3.1 type C connector will carry power, displayport and legacy USB.

The only remaining problem is software: iOS and Android aren't well suited for a keyboard+mouse+big screen interface. I bet that both Apple & Google are working on that.

Ubuntu obviously is.
