Preview: Microsoft Windows 8

Windows 8 is the next version of Microsoft Windows, a family of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, servers, and media center PCs. It adds support for ARM microprocessors in addition to the traditional x86 microprocessors from Intel and AMD. Its user interface has been changed to make it better suited for touchscreen input in addition to the traditional mouse, keyboard and pen input.
Microsoft has not yet announced a ship date for Windows 8, although some major media outlets speculate it might be available in late 2012.
