In a new piece, ZD Net argues that the end of Windows 7 marks the real end of the PC era. The writer points out that the PC reached its high point around the launch of Windows 7 and that nowadays the market looks very different with the rise of the smartphone and tablets:
PC sales have been in decline for the last seven years; a slide which only ended with a small increase last year, largely because businesses needed to buy new PCs to run Windows 10, after bowing to the inevitable and upgrading.
In many scenarios and use cases the PC has been superseded by the smartphone, the tablet or digital assistants embodied in various other devices. And it's not just the PC -- Windows is no longer the defining product for Microsoft that it once was.
