As sales of tablets and phones continue to outstrip demand for PCs, the technology industry is preparing for a shift in how people use computers.
The expectation is that phones and tablets will begin to be used as desktop PCs, a change that will force a fundamental redesign of software.
Instead of operating systems and applications having a single interface, apps will alter their look and controls to reflect how they are being used. For example, a UI that favours large, easily-tappable buttons on a touchscreen tablet might switch to tightly-packed icons when the tablet is used with a monitor and a mouse.
The idea was dubbed convergence by Canonical, the company behind the Ubuntu operating system, when it launched the idea for a phone that would double as a PC in 2013.
