I have one. Spent a year with the Drift Stealth and bought this one as soon as it came out.
The remote is much improved. The on-off beep can be heard clearly now. No guessing as to whether it's on or off. You can take photos while you're shooting a movie, no interruption involved. It is wi-fi enabled, but you don't need it. I haven't bothered with it. The remote will transmit a good 35 feet on its own, maybe more.
It's smaller than the Stealth by a good bit. Standby battery life is 4 to 6 hours. Good external microphone.
More features that are almost too numerous and I don't use them anyway. But the upside is that it's pretty darn simple to use. LCD screen on the back and a color coded light on the front so you can tell at a glance what mode you're in and if you're active or not. Plus, the remote has the same lighted color indicator. You don't need to be anywhere near the camera to know what it's doing or to change modes.
This was taken on the Ghost in just 720 mode and further reduced for Youtube use. I can show it on a 42 inch big screen and it's very crisp. I rarely shoot in 1080, but it has that option if you need it. Plus two different wide screen angles you can choose from.http://www.youtube.com/watch?v=sybw680_RKE
