Windows 8 is highly anticipated for a number of reasons, less than a month from its public debut. It re-imagines the entire concept of Windows, from icons to app design. It's the first unified operating system, designed to be easy to use on tablets, laptops, and desktops. It also heralds Microsoft's direct entry into the tablet market, with the decidedly different Surface and its keyboard covers. From the touch screen-friendly features and navigation, to the strictest standards Microsoft has ever demanded of its hardware partners, Windows 8 and the Surface line are expected to force a revolution in how we think about touch screens and operating systems -- even if consumers balk initially at the sweeping changes.--Seth Rosenblatt
