Big hit with the YouTube Generation
I'm sure there will be throngs of highschool kids that will embrace this technology, should they discover it. It would only be midly amusing for older people that aren't easily amused.
Maybe some specific industries could use this technology. Any service industry where you could allow customers to keep an eye on the workers at any time. If they find a way to mount a camera phone on a helmet or something you could have one for each worker in the field, allowing customers or the boss to see what they're doing at any time. Or even call a colleague for a 2nd opinion.
The technology is at most mildly useful for most people over the age of 21.
