And so, at Steve Ballmer's keynote, the company announced that the next version of Windows will support not only x86 offerings from Intel and AMD - themselves moving closer to ARM-like system-on-chips - but ARM designs from companies such as Qualcomm and NVIDIA as well. Microsoft noted that the new chip support was requested by its partners, implying that PC companies want to take advantage of the long battery life and thin form factors enabled by ARM architectures, but also bring along Windows' broad driver and software support. Microsoft clearly considers the tablet another PC, albeit one that Windows' hardware and user interface layer needs to support better.
