Microsoft Needs to Decide if Windows Is for PCs or Tablets
The background to this is that Microsoft is facing a disruptive threat from tablet and smartphone computing platforms. These mobile devices have dramatically different user interfaces optimized for taps and gestures rather than keyboards and mice. With Windows 8, Microsoft tried to create an operating system that could be all things to all people. A new generation of Windows 8 applications were supposed to work well with a keyboard and mouse the way PC software always has. And they were also supposed to work well on a new generation of Windows-based tablets.
But the result was a mess. Old users found the new interface confusing. New users found it clunky. No one was as excited about it as people are about iPads and Android phones.
