Yup, some of the features are nice. Though some of them seem to create new frustrations for me.
1. I like being able to drag applications to a new desktop and have the cube rotate to the desktop. This seems to make it so that I can't use the very edge of my screen, where my vertical scrollbar is (for any app), to scroll up and down. I can do it if I move a pixel away, but I usually like to just mouse to the very right and click/drag up or down.
2. The wobbling is cute, but it's imperfect and will sometimes shake for a while and adjust itself to a position close by NOT where I had intended.
