The man who succeeded Bill Gates as Microsoft top visionary, believes the world has moved past the personal computer.

Ray Ozzie,  said that Microsoft could be left behind because it did not see this quick enough.  He thinks that the PC has been nudged aside by powerful phones and tablets running Apple and Google software. He said that people should not argue about 'are we in a post-PC world?' when we already are. He said that did not mean the PC died we just call them something else.

Ozzie was making his first public comments on Microsoft since stepping down from the tech giant abruptly in 2010.
