It's GREAT. I used LiveMotion 1.0 extensively, and I'm not quite sure of what all is new in LiveMotion 2 but from what I could see, it's lookin' good. The move to OS X appears pretty seamless, although previewing animations inside of LiveMotion is a bit slower than 1.0 ... ie. it's not realtime, no matter what, on an iMac G4 with 256 MB of RAM in OS X. However, you can pretty easily use the Preview In... command to switch it to IE, where it runs at normal speed. Other than that little speed problem, it seems great.
