It's 10, Windows 10, the Microsoft newest OS proposal

Today, in San Franciso, Microsoft introduced the next iteration of its ubiquitous OS under the moniker of Window 10. Not exactly what the media were suggesting in the previous months to this great event, that is, "Windows 9" as the logical next version to Windows 8. Windows 10 will be available by late 2015 and it will (as quoted by The Verge) "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." From my viewpoint it's simply a wonderful remake of Windows 7 and Windows 8.1 plus all the good things of a universal OS running on different devices, with different form factors, tightly integrated to the Cloud. We, enthusiasts, are waiting on tenterhooks to sign up for the Windows Insider Program, not yet released as of this time.
