There's a pretty sweet video over on Eurogamer that has Richard Marks (no, not that Richard Marks) showing off a bunch of tech demos for the Move.
I was totally on the fence about Move, but these demos have actually almost sold me on the device, assuming some decent games come out that make use of the ideas on display. If they release the thing where you can build with virtual Lego (it's about 9 minutes in) then I will buy it instantly. I mean, LEGO!!!! VIRTUAL LEGO!!!!!!
Anyway, it's interesting stuff so give it a watch.
