CowboyRobot writes "The metaphors and conventions of mobile apps on phones and tablets are now driving the design of desktop software. For example, dialog boxes in typical desktop software used to be complex, requiring lots of interaction. But these are now typically much simpler with far fewer options in a single pane. Drop-down menus are evolving, too. The former style of multiple cascading menus is being replaced. Drop-downs today have a smaller range of options (due to mobile screens being so small and the need to have the entries big enough that a finger touch can select it), and they never use the cascading menu. In Web-based apps, the mobile metaphors are finding greater traction as well. One need only look at the new Google Mail (GMail) interface and see how it's changed over the last year to view the effects of this new direction: All icons are monochrome, the number of buttons is very limited, and there's a More button that keeps the additional options off the main screen."
