The upcoming 4.0 reference release of Apple’s iPhone OS will
deliver new support for running multiple concurrent third party
apps, and allow users to switch between them using a windows
management mechanism similar to one made popular on the company’s
Mac OS X operating system. […]
Those familiar with the design of iPhone 4.0 said that the user
interface will resemble Apple’s desktop Expose feature, in that a
key combination — reportedly hitting the Home button twice —
will trigger an expose-like interface that brings up a series of
icons representing the currently running apps, allowing users to
quickly select the one they want to switch to directly. When a
selection is made, the iPhone OS zooms out of the Expose task
manager and transitions to that app.
Where by “familiar with the design”, they meant “making shit up”, unless by “Exposé-like”, they meant “not at all like Exposé”.
