So, i guess, n9s swipe ui is patented thats why they cannot do horizontal swiping to get to running apps view or launcher view. But then, horizontal swipes can take to another page of launcher icons or to additional pages of a running apps, like android or any other ui. If it's not also patented.

Or could launcher and "minimized" apps page be altogether combined, that would be even better, imho. Apps launcher icon (or tile) can behave as live preview and be of double size when app is running but minimized, for example. That would be coolio!
