Future BlackBerry Playbook OS concept

Well heres a concept i made that is a future design concept of the blackberry playbook, with multiple homescreens, the way you would switch the screens is scroll with 2 fingers across the screen. So you can keep the card-like multitasking!

.....interesting

its not the best concept and it needs some better design, but it was just a little thing that would be cool to think about.
