Feast your eyes on the first look at Windows 8. The walkthrough shows the most striking revision to Microsoft's 25-year-old operating system and takes a lot of touch-controlled elements from Windows Phone. Visually, it's high-style and flashy but at least its original and different. What is interesting is we're seeing elements of mobile operating systems making it to the desktop. It's happening with iOS and OS X Lion and apparently Windows 8 is getting its fair share of the Mango treatment.
