You know, I kind of detest all that bling that adds no real usability benefits. That 3D cube for example is nothing but a propped up virtual desktop, storing one on each side of the cube. Which Linux has been doing for quite some time without crippling the machine's performance.
Personally, as far as interfacing with the machine goes there's nothing better than Quicksilver. It went open-source at the end of last year so you linux geeks might get a release at some point in time.
