Windows 10 is all about balancing the demands of different users. Its not just business users with desktop PCs and keyboards, versus tablet users. Windows is for sensors and data centres and Windows Phone and Xbox One as well as tablets and laptops and desktop PCs and giant wall screens and all the devices in between(at least in Microsofts ambitions).
But what were seeing in this first technical preview release is very much about balancing the heritage of two decades on Windows with the new world of touch, and with making IT teams comfortable with the BYOD and consumerisation features introduced in Windows 8 by giving them more security options and more management. At the preview event, there wasnt a touch screen in sight and we only got to use Windows 10 with a mouse and keyboard on a big screen that takes full advantage of the new ways of arranging windows and swapping between virtual desktops.
The technical preview is designed to make power users happy, not change the hey - the copy is done for the world.
