The $249.99 camera is the most light weight in its class at only 3 oz.
The WingmanHD takes 8MP stills, 1080p video with a 150 degree lens, has a 1.5" color LCD display and offers 3x digital zoom. Just like the GoPro, it comes with a waterproof case (30m).
I already own a GoPro, so I doubt I'll be making the switch, but for newcomers to the action camera market this looks like a good alternative.
