I'm all for portability, but when you're toting around an HD camcorder I'd like it to be big enough so that I'm not constantly worried about it slipping out of a hole in my pocket. No dice if the camcorder is this "MicroHDTV" from the Fraunhofer Institute in Germany. It's a mere 1.5 by 3 inches, which is just plain silly.
Despite the size it an purportedly pump out 1920x1080 resolution, which isn't too shabby. HD helmet cams, here we come.
