“…mobile patterns rely on both device user interface style and platform. Whereas tabs are a useful mechanism on a stylus-driven device (web or local application), they are less useful on a scroll-and-select device application, and should be implemented as horizontal navigation instead. The same navigation in a web browser on a scroll and select device should either avoid the problem altogether, or use a drop-down list.
“Since good design depends so frequently on device characteristics, a device hierarchy is helpful when working with mobile UI design. The hierarchy organizes devices into relevant device classes, with varying degrees of specificity based on the level in the tree.”
