It is really a matter of habit and preference. Expose comes with a few cool actions when you use the Tab, Cmd + Tab, or Alt/Option + Tab after you have invoked it.It's non-linear, but I'm not sure what difference that makes in a practical sense given the time it takes to simply press tab. To have to move the cursor to a box and click is always slower and more disruptive to my train of thought.
Hadn't heard of Aero Flip 3D - looks very cool, and perhaps best of both worlds.
That does not mean that I am not also using Cmd + Tab. It is just another long list of different keyboard shortcuts, mouse buttons, or hot sides/corners. I just happen to pick which ever feels most natural to me at the time based on what I am doing or my cursor location.
Bear in mind I am still on Snow Leopard's Expose.
"skeuomorphic/skeuomorphism" has been rather popular lately. Gizmodo is not necessarily the first to use it.True true, I just find really funny that they had to come up with such a sophisticated word.
