We know what you're going to say, but trust us: Windows 8 is not only cool, it's potentially a game changer.
Windows 8 has a completely new visual interface that's unlike anything you've seen on a PC before. It's optimized for touch screens on mobile devices like tablets, but it will also work for those with a traditional mouse and keyboard setup.
The result is a computer that operates as a hybrid, with all the functions of a standard PC operating system but the user experience of a tablet. Apple says we're already living in the "post-PC world." Windows 8 is a sign that Microsoft agrees -- and if it has its way, tablets and PCs may soon be indistinguishable. -David Goldman
