Ocean Observations has worked up a concept interface for the iPhone that takes elements of the Palm Pre's functionality, combines it with Apple's Cover Flow, and makes up their idea of what multi-tasking on the iPhone could look like.

"Our idea is to present the running apps together with the rest of your app icons on the home screen, instead of hiding them behind some long pressing unrelated key", says the team behind the concept.

"All running apps have a miniature representation in a cover flow at the bottom of the screen. To make room for this, each home screen page will have one less row of icons and the dock is removed completely. But since the running apps will often equal your favourites, they will still be easily accessible".
