I use it almost exclusively on my 11" air. With limited screen space it is very helpful. And swiping directionally between fullscreen apps is more intuitive than cmd-tab.

But it is total garbage on a large screen, so I don't use it when docked.

This is very helpful. I guess it is for smaller screen sizes. It makes sense now. Thank you!
