Got mine yesterday and have been diddling with it this morning. As has been said, the WiFi base is a no brainer as it makes the OP so much more flexible and, usable. I also like the Controller Wheel and it's easier to use smoothly than I thought it would be. I can see having this in use anytime the OP isn't stationary on a base or tripod. MOST excellent news too with the FW update and Pro mode all the time. I'm really having fun with this little widget but now I gots to record some stuff.
The wheel controller was the one i wasn't really bothered about at first, but it's never been off! so much easier to get smooth a smooth pan shot. I'm hoping we get the ability to map out multiple points in standard video modes similar to the motion lapse option allowing us to do a multiple poi over say a 20 second clip.
