Microsoft has used its presentation at Computex in Taiwan to show off Windows 8 and detail newly toughened requirements. The OS' flexibility was such that it was shown on anything from a basic tablet up to performance notebooks, such as a Dell XPS or a future HP dv6 running AMD Llano that will ship later in the spring. ARM-based prototypes were on view at the same time and even included a quad-core NVIDIA Kal-El notebooks and tablets that could use hardware-accelerated HTML5 rendering, much like an x86 system.
