'Some features were stolen so long ago that they've become part of the computing landscape, and it's difficult to remember who invented what.' Windows 7's Task Bar and Aero Peek come to mind as clear appropriations of Mac OS X's Dock and Exposé. Apple's cloning of the Windows address bar in 2007's Mac OS X 10.5 Leopard as the path bar is another obvious 'inspiration.' But the borrowing goes deeper, Rizzo writes, providing a screenshot tour of Microsoft's biggest grabs from Mac OS X and Apple's most significant appropriations of Windows OS ideas and functionality."
