In the past 5 years, I've had quite a few moments that I thought 'Man, I wish I could have that as a video clip.' Unfortunately, it was just some random event and there's no way I'd wear this thing for months just to hopefully catch some 30 second segment of life.<p>But maybe others are less rational than I am and it'll result in a lot of awesome youtube clips.
I would definitely consider buying something like this if it could be built into glasses to look less obnoxious. Additional bonus if a wi-fi hard drive could be added for longer recording times.
