My dad won a Go-Pro at some golf tournament....so he strapped it on and filmed my parents' vacation....driving around New England going to all the old people stuff lol. He was prolly giddy and my mom was prolly ashamed.
depends what you like to do...for concerts, or large events, or if you like nature it's certainly worth it.
It's hard to say. I don't use mine all that much but it's nice to have a camera that you don't mind taking to a concert, festival or out on the boat. I am looking forward to trying it while snow skiing this winter. Just depends on if you don't mind spending the money on having a toy you use sporadically.
