Microsoft presented Windows 10 instead of Windows 9.  Windows 10 will run across an incredibly broad set of devices – from the Internet of Things, to servers in enterprise datacenters worldwide. Some of these devices have 4 inch screens – some have 80 inch screens – and some don’t have screens at all. Some of these devices you hold in your hand, others are ten feet away. Some of these devices you primarily use touch/pen, others mouse/keyboard, others controller/gesture – and some devices can switch between input types.
