I ordered mine Sunday and it was at the house this afternoon. I didn't get to mess with it much before heading to work, but man, that thing is tiny! I'd say it isn't much thicker than a deck of cards, and about the same dimension tall and wide. There are so many different features with this camera, I'm not even sure where to begin.
I got the Black Version, along with coming with a wireless remote, the camera is also beefed up in the resolution and processing power departments (compared to the silver and white). It will film 1080p at 60fps and 720p at 120! I'm anxious to try some stuff on it @ 720p, and then replay it in slow motion.
Overall, I'm happy with the purchase initially, just gotta figure out how I intend to use it!
