no ui can be better than swipe on n9. Jolla, it is time to copy, use or license it. Nokia will not sue you i need a pure touch(no button) os with swipe to go back to homescreen. Ipod nano have this basic feature if i am not wrong. It will be a waste if we never see swipe again. Btw maemo6 ui concept revealed in 2009 is not too bad.
