The VERGE report suggests that the process of convergence is already underway, as the LEED system and ASHRAE standards continue to drive changes in efficiency, telecommuting increases, and a move back to cities occurs.

"We are defining a new era of convergence in technology, with one unified operating system that underpins cloud computing, data centers, PCs and consumer electronics" says Mark Shuttleworth, founder of Ubuntu and VP Products at Canonical.
