Dozens of people camped out all night at the Microsoft Store in Seattle's University Village to be among the first to get their hands on the new Windows 8 operating system Friday.
Windows 8 represents the software company's effort to address the growing popularity of smartphones and tablet computers, namely the iPad.
The new software is a radical departure from previous versions of Windows. It may take people time to get used to the changes. The familiar start menu on the lower left corner is gone, and people will have to swipe the edges of the screen to access various settings. There will be a new screen filled with a colorful array of tiles, each leading to a different application, task or collection of files.
Windows 8 is designed especially for touch screens, though it will work with the mouse and keyboard shortcuts, too.
