The MoVi device is a little bit of an anti climax from when it was announced a few days ago by Vincent Laforet as a game changer.. It really isn't.
$15k is excessive since I can do all of those moves using my Stedicam rig... The skating shot is cool, but Vinny Minton owned those shots back in 2010 using a Glidecam HD2000 and an mk2...
Seen it, done it...*
It's a cool device for sure, but I would not give up my Steadicam for it as I can use it all day long with no strain, while my camera sits happily perched on the mechanical arm.. I should imagine this will be very tiring after a short time..in fact, I know it will be.
