This kinda deal would have been hot even an year ago. but now with hi-def cameras in a lot of portable devices, some people are skipping these and instead using their smartphones, portable tablets, etc as a one-in-all device and taking crisper pictures and videos.
A smartphone camera can't compare to this because of sensor size and quality/ size of optics.
In cameras, size matters.
"Hi def" doesn't mean it takes good pictures.
