The Ghost's two-inch color LCD screen makes previewing footage and tweaking settings on the fly a snap, while its wrist remote lets you start/stop from up to 30 feet away. Submersible to nine feet, the WiFi-enabled cam aced wet runs and bike rides, nabbing HD video and big 11mp images. It's by far the most user-friendly, too. Killer app: video tagging, which made it easy to find our best clips. [$400;]
